Hoping someone can explain why, with my CYA level being as high as it is, I am able to maintain a crystal clear pool with a FC of about 4ppm. Never once had algae growth, pool always looks fantastic. I don't add any chemicals other than a few chlorine tabs each week and a pound of shock once or twice a year. Even throughout the 115 degree Phoenix summers.
I'm using a Taylor K2006 kit to test. The CYA turbidity test, both doing it as recommended and diluting it 2-fold, is amazing. The black dot disappears with only a few DROPS of the water/reagent mixture (literally 4 or 5 drops). Could something else be causing a false reading - making the water more turbid and tricking me into thinking my CYA is much higher than it actually is?
Calcium is high, alkalinity is high (sorry, don't have the numbers off hand, I can get them if it helps), pH is 7.6. Only complaint is the water tastes dull, probably cause there's more CYA than water in my pool!
12000 gallon pool, variable speed pump running 7 hours per day (3.5 hours at about 3000rpm, 3.5 hours at about 1000rpm), cartridge filter, in floor cleaning system.
I really want to switch to the BBB method. Get the pool drained, get the CYA to a more comfortable 50-60ppm, cut out the trichlor tabs. But I'm wondering why fix what's not broken. And why my pool isn't green with the CYA/FC ratio I have going on.
Thanks in advance. Always get great info from you guys.
