I'm a new pool owner, I just bought a home with a pool that was built in 2000. It's roughly 16,000 gallons. When I bought the home, the pool was a grayish green and cloudy. I took a sample to a local family owned pool store. They told me to shock it every 12 hours and brush it twice a day until clear. I also ran the pump 24/7/. My pool is now nice and clear.
Here is the problem, I can't get it to hold any free chlorine. Every time I test it I am in the 0.1-0.5 range. I have a Rainbow inline tablet chlorinator set to 5 and a float with 3 tabs in it. The pool store says not to use any liquid chlorine, that the tablets with an occasional shock treatment should suffice. I have used the Super Zappit shock.
Any tips? It seems crazy to me that the pool is not holding the chlorine.
Here are the most recent (from yesterday) results
free chlorine 0.1
total chlorine 0.1
combined chlorine 0.0
pH 7.8
hardness 345
alkalinity 77
CYA 42
