So I am a relatively new owner of a small covered pool. I have read the pool school multiple times and keep a printed copy near my TFT-100 test kit. I have not had much trouble at all adjusting chemicals thanks to this site and the pool calculator.
My question is if I should adjust my chemical targets based on having my pool covered 100% of the time unless I am actually in the pool. (The only exception is leaving it uncovered at night in the summer to lower the temperature of the water).
Here are my current numbers:
CH: 210-220 (just added another 8oz to raise it more last night, my target is 250)
My main question is about CYA. Because my pool is so small and it is covered all the time my FC can rise very easily and it takes a while to drop back down. I have found that 15% is too high a setting on my turbo cell 15. I run it between 8-10% normally (9 hour pump run time a day).
Do I still need to raise my CYA up to 70-80 when the water gets only limited sun?
Also, I have been repeatedly lowering my pH to 7.0-7.2 with muriatic acid and letting it drift up with very little success in lowering my TA. Am I doing something wrong in my attempts to lower TA?
What about my other numbers? Should I run a lower FC since my pool is covered most of the time?
Thanks for any advice.
