Hey y'all,
Thanks to your good advice things are going pretty well with my pool. My one continuing problem is that I'm having to add what I consider a lot of bleach every day to get to my target level of 4. This is usually 78, 93, or 109 oz as the FC is 0.5-1.5. I'm thinking I need to boost my CYA substantially rather than keep it around 30-40.
This is where it gets interesting. Whenever I test CYA, I can always fill the tube to the top and still faintly see the black dot. I therefore think my CYA is less than 30. I have now run out of the CYA reagent, so I took a sample to the pool store -- and they measured 71!
FWIW, I know exactly how much stabilizer I've added since refilling the pool. I've added 4 lbs of CYA and one 13.5 oz bag of trichlor shock (66% trichlor). The pool calculator says my CYA should have been raised by 34.5. (I'm assuming it's really 9 oz of trichlor). That still makes my < 30 reading fairly inaccurate.
So what do y'all think? Could I be testing wrong? And given all the bright sunny days we have here in Tucson (often no clouds whatsoever) should I bump up my CYA to, say, 60?
Thanks,
Mike
