Chlorine Tablets
How long does the tabs last
This year there is a shortage of 3-inch chlorine tablets. Places around us only have small containers. They are limiting one container per customer. (I think the prices are a bit higher this year.)
Turns out the shortage is related to the Chlorine Plant that provided a large portion of the supply burned down in August 2020. Supply got worst early this year when the mainstream media started reporting on the shortage and people started stocking up.
We use the Hayward In-Line Chlorinator. We purchased it last year, and it survived being outside in the harsh New England winter. I think this Fall I'll move it to the basement just to protect it from the elements.
Chlorine Tabs
I am able to fill eight tabs in the chlorinator container. I have found that that it lasts for 10-days when the setting is on high. I tested this a couple of times and can verify that it lasts 10-days when you fill the container up.
We have a 24-foot round pool that holds about 14,645 gallons.
The average pool season in Massachusetts is from Memorial Day to Labor Day. In 2021 that's 98-days. That means that we'll be using roughly 72 choline tabs.
The pool is looking great this year. The only issue is that the water has been too cold to swim in.
