Hi all, I have read it all, on this site, learning more then I thought I needed to. I like how everyone answers with such good information that is backed up by fact.
I just opened my pool Friday, looked clear at first but, started to turn green fast. I shocked it at 15 PPM for 48 hours and then started letting the FC level drop on its own. The green turned to white cloud, and now the pool is clearing nicely. Back flushing every 6 hr or so. I have been using the calculator but have some reservations...
1. Do I want to use traditional or trouble free pool numbers?
2. My 100 pound sand filter with new sand reads 15 psi. When it gets to 25 I back flush and it returns to 15 psi. I see In quit a few post that other peoples sand filters run at a lot lower pressure. Not sure if im ok here??
3. Earlier today FC 1.5, PH 6.8, TA 120, CH 250, CYA 70 : I started aerating and bought BORAX but have not put it in. Added Bleach and brought FC up to 6.0, aerating has brought PH to 7.3, and all other readings the same...TA 120, CH 250, CYA 70. If I stop aerating will the PH drop again? How would I correct this if my PH drops to 6.8 again seeing if I add acid it will drop my PH further, and If I add borax it will raise my TA from the calculator 16 (ouch).
Thanks in advance for your comments...
