Everything seems to be going well in my first BBB summer, but just wanted to get a little fine tuning advice (or at least explore differing opinions, as I know that after a while pool control becomes quite a personal process). Saturday am numbers are:
CYA 30 (I had this up to 50 but had to drain twice due to heavy rains).
My questions are as follows:
(1) TFP-100 instructions recommend TA 100-120. Jason's Pool Calculator recommends 70-90+. I assume I am OK as is and that for my pool an acceptable range would be 70 - 120. In any case, I am able to maintain pH at a steady 7.5 - 7.6. Any adjustments needed?
(2) My CYA is now at 30 and I have maintained a 30-50 ppm range all season. I adjust FC accordingly to Pool Calculator mid-range value. No algae, sparkling water, etc. A+ rating from my pool inspector (wife). I find that I have about a 3 ppm FC loss due to sun and use no matter where in the 30 - 50 CYA range I am. I have read that above 20 ppm CYA efficacy diminishes. So.....what are the experiences/recommendations of the forum (and I will likely do whatever I think is best anyway )?
