I cant keep chlorine in my pool


Jun 2, 2018
I had a brand new 30 x52 installed 2 weeks ago. It has a built in chlorinater. I keep it full of tabs and I have the dial turned up as high as it will go and the chlorine still registers zero.

The only thing the pool place did was to shock it and add algaecide.

Don't I need to add stabilizer? If So, what's the easiest way to add it? It's approximately 21,000 gallons.

It does set out in full sun.

yes, you need stabilizer to protect the chlorine from the sun. at least 30ppm of cyanuric acid.
BUT, unless you have a great test kit (tf 100 or a k2006c) you’ll be shooting in the dark on how to maintain that pool
