Sand Filter

Sand Filter

Here are some of the information on our Hayward Pro Series filter (Model: S180T), this is approved for fresh or salt water.

The filter can handle 20 gallons per minute. Which means for a 14,645-gallon pool it will take at least 1.63 hours for the filter to process all that water.

The maximum working pressure is 40 PSI. If your pump handles more than that, you?ll need a different type of filter.

The filter can hold 150 LBS ( 68 KGS) of filter sand. It's critical to have exactly that much. If you only put in 125 LBS, you?ll make the filter less effective.

Operating Instructions

  • Be sure correct amount of filter sand is in filter tank.
  • Set Vari-Flo control valve to BACKWASH. CAUTION: All suction and discharge valves must be open when starting the system. Failure to do so could result in severe personal injury and/or property damage.
  • Prime and start pump, allowing tank to fill with water. Once flow is steady out waste line, run in BACKWASH for 2 minutes.
  • Stop pump, and set valve to RINSE. Start pump and operate for 1/2 to 1 minute.
  • Stop pump, and set valve to FILTER. Start pump. Filter is now operating in normal filter mode.

Filter and Control Valve Functions

  • Filter - Set the valve in FILTER for normal filtering. Also use for regular vacuuming.
  • Backwash - For cleaning the filter. When filter pressure gauge rises 6-8 PSI (0.41-0.55 bar) above start-up (clean) pressure, stop pump, set valve to BACKWASH. Start pump and backwash until water in the sight glass is clear.
  • Rinse - After backwashing, with pump off, set valve to RINSE. Start pump and operate for 1/2 to 1 minute. Stop pump, set valve to FILTER, and start pump for normal filtering.
  • Waste - To bypass filter for draining or lowering water level and for vacuuming heavy debris directly to waste.
  • Recirculate - Water recirculated through pool system. bypassing filter.
  • Closed - Shuts off flow from pump to filter. Useful when you are cleaning debris in the pump.
  • Winter - For winterizing. (SP0714T)

Winterizing Instructions

Set control valve in WINTER position, Remove drain cap and throughout drain filter. Drain pump per manufacturer instructions.

We keep the base filter outside, covering it with an installation and a tarp. We put the top inside our basement. I make sure to keep all the loose parts in a bag and attach it to the filter to make opening the pool very easy.

Water Evaporation

A concern that some above ground pool owners have is when to determine if the pool has a slow leak. You may notice that the pool level slowly goes down, is it a leak or is just natural evaporation.

Adding Water Everyday?

If you're putting water in the pool every day, chances are you have a slow leak problem You should double check all patches to make sure that they are secure. It might be a good idea to double patch areas for a better seal.

There is some pool specialist that can check for the source of the leakage by using sophisticated sound and color dyes testing.

Natural Causes of Water Evaporation

There's no exact amount of water you may loose every day since there are four key factors that determine evaporation: exposure, water temperature, and humidity.

Exposure is how much sun and wind the pool gets everyday. Sun is great to warm up the pool, but those rays also burn off a tiny amount of water. Solar covers are a great way to prevent evaporation from exposure.

Water Temperature - As the pool heats up during the day, it cools off at night. That cooling off period is when some evaporation happens. Turn on the pool light on a nice summer night and you'll see the mist of water evaporating from the pool.Cause

Humidity - The more humid the environment, the less evaporation that will happen. Which means during a period of dry weather, you would expect to see a bit more evaporation.

In addition, constant use of the pool will cause loss of water.

The Bucket Test

The best way to test for evaporation is by using the bucket test.

Take a 5-gallon paint bucket from Lowes or Home Depot. Make a mark with a permanent marker at about the halfway point. Fill the bucket with pool water, so it?s the same temperature and has the same chemicals, up to that point, and set the bucket right beside your swimming pool. Simultaneously, use a pencil to mark the water level on your pool skimmer basket. Mark your skimmer basket so that way you don?t ruin the liner with a marker.

This test will help you determine how much water has evaporated from the bucket and from the pool. Make sure to turn off any pool heater during this test.

Pool owners use Cyanuric Acid to help prevent the loss of chlorine due to sunlight exposure. Cyanuric Acid is also known as CYA, Conditioner or Stabilizer.

If you have an outdoor swimming pool, you should beware of the Cyanuric Acid levels in your pool. Ignore it and you could be significantly be reducing the chlorine levels in your pool because of the hot summer sun.

Each state has different regulations on the amount public pools should have. In Massachusetts, public pools should have at least 30 and no more than 100 ppm. New Hampshire has no standards. In Maine it should be at lease 10 but no more than 150 ppm. Connecticut public pools should be no more than 100 ppm.

In Florida, which has the most private and public pools than any state, requires that all public pools be no more than 100 ppm.

Check out the various requirements over on Pool Operation Management website.

To high Cyanuric Acid levels?

Having too high Cyanuric levels will weaken the effectiveness of the chlorine. Higher levels will bind with the chlorine, making it slower acting to kill bacteria and microorganisms, and prevent algae. Higher levels will also increase cloudiness in the pool water.

Your best solution to fix a pool with high Cyanuric Acid is to backwash some of the pool water and put in fresh water.

To little Cyanuric Acid?

Too little Cyanuric Acid will results in more of the Chlorine being burn off.

Add the right amount of CYA, Conditioner or Stabilizer based on the current levels and how many gallons are in your pool.

How to test for Cyanuric Acid?

The AquaCheck test strips checks for all the critical pool chemicals. They have an App for expanded water analysis and prescription water balance. (Andriod and iOS) It's a good way to get more detail about what you should do with your pool.

On the AquaCheck test strip container, the follow text appears at the bottom:

For best results on Stabilizer test, pH should be between 7.0 - 8.4 and Alkalinity at or below 240 PPM

In other words, make sure the rest of the pool is balance before being concern with the results of the Stabilizer test.

Total Alkalinity

Total Alkalinity2

Pool owners need to have a stable Alkalinity to prevent potential maintenance cost resulting from damage to pool equipment. Pool pump motor life can get cut short because of plugged filters and reduced pipe flow from scale build up.

In addition, Imbalanced Alkalinity may cause burning in the eyes and itchy skin.

The main reason to be concern about the Alkalinity in your pool is because it a measurement of how to balance your pool really is. If you have too high or too low levels of Alkalinity, you're going to have a hard time balancing the pH and Chlorine. Thus you'll be spending lots of money to balance the pool.

The ideal Total Alkalinity should be somewhere between 80 and 120 ppm.

High Total Alkalinity

The results of high Total Alkalinity may be one or more of the following:

  • Cloudy water!
  • Not able to keep the ph in balance despite regular addition of pH-down;
  • Reduced chlorine efficiency resulting in algae growth;
  • Added too much baking soda, when trying to increase your total alkalinity.

There are two main chemicals available to lower alkalinity: sodium bisulfate, also known as dry acid, and muriatic acid. You can find muriatic acid at Lowes and Home Depot, check the pool supplies section and/or the paint supply section.

Low Total Alkalinity

The results of a low Total Alkalinity may be one or more of the following:

  • Staining of the pool's surfaces
  • Slightly Green water
  • pH bounce (rapid fluctuations in pH).

To raise Alkalinity: use Sodium Bicarbonate (Baking Soda). Most experts suggest using One pound of Baking Soda for every 6,000 gallons of water. Simply pour the baking soda slowly over the out spout. Just make sure to test the Total Alkalinity levels after a couple of hours to make the pool is fine.

pH Levels

Why test the pool for pH levels?

p H Levels

Pool owners use pH test to see how acidity or basic the water is. They measure the pH on a 0 to 14 scale. A reading of '0' means that the water is very acid, and a reading of '14' means the water is basic.

The ideal reading is a 7.4, which is the same pH balance as in the human eye drop. In addition, it gives good chlorine disinfection. Having the pH at 7.4 will help your chlorine be more effective. When your chlorine is effective, you're getting the most use whether you shock the pool or use a Chlorinator.

If you're using the pool testing strips you don't want a bright pink or orange reading.

What causes the pH level to go Down?

Poor Chlorine. Chlorine and pH work together, if you have low Chlorine, then chances are you have low pH levels. Get the pH up first so that your Chlorine can be effective.

What caused the pH level to go Up?

The most common cause is rain water, It doesn't hurt to check the pool immediately after a rain storm. Over time, the sun can burn up the chemicals and cause higher pH levels.

Before you get too concern about the Ph Levels

Check to make sure that your pool is clean. If you have lots of dirt, leaves and debris in the bottom of the pool, focus on getting rid of that before being concern about the pH levels. You're never going to properly balance the pool if you still have a lot of leaves and debris in the pool.

Once the pool is nice and clean, balance the pH then make sure that the Chlorine levels are good.

Liquid vs Crystal Shock

What is the best Shock type to buy? When is the best time to use the liquid version and when is the best time to use the power version?

Pool Chemicals

What is Super Shock?

Shock is a sanitizing chemical of water. Shock contains highly concentrated Sodium hypochlorite solutions.

Liquid vs Crystal Super Shock

There is very little difference between the two varieties. When using the Crystal Shock, most manufacturers recommend to delude in a bucket of pool water rather than pouring it directly into the pool.

Using the liquid form just makes it easier to shock the pool, Simply just pour it directly into the pool.

Liquid shock is harder to find, although most pool places do carry it. You'll find the Crystal Shock at most box hardware stores.

Best Time to use Liquid Shock

The best time to use the liquid shock is opening the pool. You won't have crystals falling to the bottom of the pool, only to be picked up by a floor vacuum.

Penalty for Over Shocking

If you over shock the pool, you get a couple of penalties:

Pool Liner Discoloration

If you put in too much Shock you will bleach the pool liner. Very soon you'll have a ring around the pool. The only way to fix this is to replace the liner!

High PH levels

The pool may look cloudy because your PH levels are off the charts. You will need to fix this by adding a "pH Decreaser" to reduce the acid levels. Once you have control of that, the pool should look much better.

Lesson Learned

Make sure to wear proper clothing when applying any type of mega shock to the pool. You could encounter unexpected backsplash which will stain your clothes. Tip: Wear light color clothing, don't forget about the shoes!

Make sure to evenly spread the shock around the pool. I find pouring near the filter. Outtake helps spread it around better.

Once Shock is added to the pool, you must wait 2-3 hours before anyone goes in the pool.

Always apply shock in the morning or early evening. Adding during the middle of the day will only burn off some of the Sodium hypochlorites. Thus losing strength and power of the shock treatment.

If you're getting the Crystal shock at the hardware store, pick up a store 5-gallon bucket to mix the shock. The bucket and cover is a good container to store the crystal shock packets.

You can always use the sand filter backwash to easily get water into the bucket.

Above Ground Pool Supply Essentials

Pool Essentials

Here's my suggested list of five pool supply essentials that every above ground pool user should have at their disposal at all time. Not having any of these could mean an unscheduled trip to the pool store. That is if they are open.

  • Pool Patch Kit with Glue
  • Extra Hose with Clamp
  • Shock
  • Plumber Tape
  • Pool Water Test Strips

Pool Patch with Glue

A Pool accident can happen at any time. You never know when something will inadvertently hit the pool. We have had a tree branch and a rock from a lawnmower break the liner - within a few days of each other. Chances are when something happens, you won't have much time to run to the store.

Extra Hose with Clamps

Having an extra hose is extremely valuable when one of the hoses suddenly breaks. This is more likely to happen early in the season when hoses have worn out after many years of use. Extra hose clamps are good in case the old clamps rust out and you can't tighten them any more. Make sure to have at least one available for each length you have.

Just remember to store your hoses inside so the cold weather doesn't shorten the lifespan of the hose.

Extra Super Shock

You never know when you may need to super shock the pool. You don't want AFR or accident to ruin a great swimming weekend.

Remember that liquid super shock does hold its strength for more than one year. Don't over stock on liquid Super Shock - even if it's a good sale!

Plumber Tape

This is handy to have when opening up the pool and you want to make sure that water does leak from the pipes. You can find these a bit cheaper at the big box hardware stores.

Pool Water Test Strips

Always make sure that the pool is well balanced before anyone swims in it. The pool might look super clear, but there might be a chemical imbalance that could cause someone to be sick. It only takes a minute to get a quick read on how safe the pool is.

The Pool Water Test Strips is a quick and easy way to find out if the pool is ready to be used.

It doesn't hurt to have just enough amount of chemicals to balance the pool. It helps to know how many gallons are in your pool.

Always be Prepared

I also keep a spare screwdriver and pliers in the shed. That way if I need to tighten, or loosen any pipe connectors I don't have to go looking for the right tools.

Have all of these will make sure you're ready for a perfect pool summer. Try to think of other supplies that you may need and share your emergency kit ideas!

Liquid Pool Shock Shelf Life

Watch out if you're buying a lot of liquid pool shock to stock up this summer season. You should only be buying enough that you will need for this season. Liquid shock does not store very well as it looses its strength as time goes on.

Plan how much shock you need for the rest of the summer. Don't be fooled to stock up when the local pool place has an end of season clearance. Get only what you absolutely need!

In addition, don't put too much shock when you close the pool because it will only discolor the liner. This will cause a weird looking ring around the pool. The only way to fix it would be to replace the liner. Thus putting too much shock could be an expensive mistake.

So what do you do with any extra shock inventory? You can still keep it - as stores perfectly fine in the pool shed for the winter. Just keep in mind, that when you use it next spring, it won't be that strong strength. You won't hurt the pool by putting it in, but your not getting your money's worth as it won't be that strong.

The next time when you shock the pool with several liquid pool shock containers, and you don't see and change in PH levels or the pool is still green, you were probably using old liquid shock containers.

Lessons of a Pool Owner

My personal list of lessons learned from managing an above ground pool in New England.

Make a note of anything that you'll need to buy in the fall (Missing pieces, broken pillow)

When you plan ahead, you will save time and money. Some pool shops will have special deals throughout the spring on leftover fall inventory. Also if you don't need it right away, you can order online and select the cheapest shipping option.

You could save on buying pool covers to make room for the new inventory or in some cases on fairly used one on Craigs list.

Some common things you may need: Pool Cover, Cover clips, ropes, better chemicals, side brush, bigger leaf rake and a new pillow.

Keep everything together.

When you put the winter supplies away, keep things together so that it will make it easy to close the pool in the Fall. It would be very handy to know where the pool cover clamp is. Oh, and storing the cover clips in a grocery plastic bag makes it easy to find in the Fall. I hang the bag on a nail in the back of the shed. Same place every year.

Make sure to spend extra time cleaning the cover and allowing it to dry before folding. This will ensure that your cover has a long life. 30 years above ground covers don't exist, if you have it for more than 5 years you are batting above average.

Test the pool chemicals before turning on the pool filter

The first thing to do when getting the cover off the pool is to test the chemicals. This is your base. Add any water and the run the filter and test the chemical level again. It should be different because of the chlorine and water movement. That's what you should bring to get tested at the pool store.

Check the sand filter drain before starting the filter

This is key. Before starting the sand filter double check all the end points and make sure they are tight. You don't want it too tight, but it needs to be secure.

Don't run the filter unattended for the first few hours!

You never know what can happen. You may have a worn out hose or the water pressure may pop out the filter drain. You should be near the filter to respond to any unexpected action that happens.

In 2011, we encountered a situation where a hose had a tiny hole in it because of how it was stored. The hole didn't show up until about 20 minutes after running the filter. The water slowly shot out of the house until it got bigger. Lucky that I was around to turn off the filter and then stop the water while I replaced the hose.

Take inventory of what chemicals you have in stock before going to the pool store.

When you get the pool water tested, you should know what you have in the shed and more importantly how much you have. Don't forget to check the dates too ! Do you have any Aligicide, PH Up or down?

Knowing what you have on hand can help make sure don't waist chemicals that you do have on hand. Also make note if you need to stock up on other supplies. Most patch kits rubber cement only last one season. Do you have and extra hoses? How about clamps? You don't want to be caught off guard if an accident happens.

Know your pool!

How many gallons is your pool? Don't go by what the package says because you may have more or less water than you think. Measure how much water is in the pool and the times it by the width.

This will be extremely useful as you'll know how much chemicals to put in. You may find that your not putting in enough and that's why it takes forever to balance the pool.

Keep a Pool log

Having a log of what you do to the pool will help future similar situations. It's also useful tracking all the chemical expenses. So if it seems that chlorine appears to be more expensive in August, you'll know how much you paid. In addition you'll know exactly how much chemicals you use in a season so you can make wise decisions on when to buy things in bulk.

You don't need to be fancy with a logging. You can use any notebook and a pen. You can even have an envelope and record things in the off-season for future reference. Key thing to record are the dates and why you took action.

Some example logging:

July 4 - Added 3 cups of PH down after a heavy rain storm
July 6 - Spent an hour cleaning the side of the pool for the party
August 3 - Removed dead bird from pool

We found the local pool places are not very helpful in the middle of the summer. Usually the summer help isn't always that knowledge. So keeping ahead of the game is certainly key, otherwise you may pay for some bad advice.

Green Pool Fix

Here's how we have been able to convert an ugly green pool into a nice clear pool that everyone wants to swim in. It doesn't take a lot of work, just time and patience.

Note: We have a 14,645 gallon (52996 Liters) size pool.

Shopping List:

  • 4 gallons of Liquid Shock
  • Algicide (16 oz)
  • First Aid pool cleaner

Day One:

  • Turn on the Pool Pump and Filter
  • Run the Filter backwash for about a minute.
  • Dump the 4 gallons of Liquid shock into the pool. Make sure to pour each gallon in a different part of the pool. Be careful when you do this as some of the backslash may stain your clothes.
  • Put in 7oz of Algicide in the pool. Make sure to spread the amount all over the pool. I like to make sure that the center of the pool gets plenty of Algicide since when the pool runs most of the allergy will move towards the center.
  • Run the Pump and Filter for at least 10 hours

Day Two:

The pool should be less green with some white, now it's time to clear it up.

  • You should run the Filter Backwash for a couple of minutes.
  • Put in 1/2 the bottle of First Aid in the pool, again making sure to spread the amount all over the pool.

Day Three

Pool should be less white today. If not, add a bit more of the First Aid and then follow the next steps.

  • You should run the filter's backwash for a couple of minutes.
  • Run an automatic pool cleaner for several hours. This is important to run to completely remove all the dead allergies that have floated to the bottom of the pool. You won't get the pool completely clean until they are gone.
  • We love to use Diver Dave. Diver Dave is a highly efficient automatic pool cleaner that crawls around the flat bottom of your above ground pool eating up most everything in sight.
  • After running the automatic pool cleaner for several hours, you should run the filter's backwash for a couple of minutes.
  • Run the Pump and Filter over night

Day Four and Five

Run the filter's backwash for a couple of minutes.

  • Continue to run the filter for 8 hours, you may need to add some additional Algicide or First Aid depending on how bad the pool looks.
