I'm struggling to get my pool clear this year (my first time overwintering a pool). I have an Intex 22' x 52" ultra-frame pool with a 2500 GPH filter pump and a SWCG. I have really nasty green algae that I've been trying to get rid of. It's been clogging up my paper filters which I have to keep cleaning every couple of hours. Prior to testing, I added several bottles of standard bleach. I then tested the levels this last weekend and they were:
FC: 19 (forgot to test CC, though!)
Calcium hardness: 90
The numbers above were produced with some "assistance" from my 5 year old, so they are a tiny bit suspect (I trust the numbers below more). Since then, I added a couple of shock treatments: 1 bottle of Clorox Shock Xtra Blue and 1 bottle of Clorox Shock Plus (yeah, I know--shouldn't have bothered, but I was getting frustrated). Today I tested again, but ran out of FAS-DPD reagent so I will order more. But, I tested the other numbers and have:
Calcium hardness: 80
I used some test strips to test the FC and CC and they appear to be in the 10-15ppm range.
So, what now? My first thought is that I need to add sodium bicarbonate to fix TA. Then, add some calcium chloride to improve the hardness. Then, test the pH and fix that. Then what? Do I need to do all of that and then report back?
Thanks for your help!
