Pool 22,500 gal, plaster, solar heat, temp 86. CYA: 100. pH 7.5. Typical CL levels: FC: 1.0, CC: 0.5. Last replaced about 1/2 pool water 2 years ago. We have well water, which is hard.
I used floater with 3"tabs for years, but gave up because the only way to find chlorine in the water was to take the sample from INSIDE the float. My neighbor uses a double chlorinator, which I went out and bought. Result after 24 hrs: FC: 0.5!
I am adding chlorine twice a day: liquid 10%, dichlor or Ca hypo just to maintain decent levels. I typically have FC 1ppm, CC 0.5 PPM. I have shocked with all kinds of powders, as well as Leslie's Fresh N' Clear. The water is crystal clear, there are a couple streaks of green on the tile grout near the skimmer inlet, but no slime and otherwise looks fine.
Help! This twice a day chlorinating is driving me nuts.
