Weird Levels

[aylad]

Watermom and I rarely diverge on our advice-giving, but I just wanted to throw something out there....you now have a nice, clean, clear pool, and Watermom has given you great advice about testing daily to get a feel for how much chlorine your pool uses and roughly how much you'll need to add. However, if you feel that you're still using too much chlorine in a day's time (different pools with different sunlight exposure, temps, etc vary in how much chlorine they use), you might try bumping your CYA up just a little bit to see if that slows your chlorine loss any. When you raise your CYA level, you'll also have to raise your minimum chlorine level, but you might find that you lose less chlorine overall with a slightly higher CYA. I run my pool at 80-90 ppm CYA on purpose, because that's the point where I lose the least amount of Cl in a day. It means I have to maintain chlorine levels of 5-10 ppm, but I only lose 2 ppm or so daily, where if I tried to run a CYA of 50 ppm pool, I would lose 4-5 ppm daily. It also allows me to dose every 2-3 days, rather than every day.

Just something to consider.....

Thanks to both of you. Our pool is in direct sun all day until about 6 pm. Running a slightly higher cya level is something to think about. Will monitor daily for awhile to see how much cl we lose daily.
