I have been shocking my IG concrete pool with around 15 ppm CL since opening, a week and a half ago. It was green like a pond. Now I have a nice blueish couldy water but it is showing some white foam on top.
CYA: 40
FC: 13
CC: 1
pH: 7.5
TA: 140
CH: 150
The Ph was above 8.2 to start. Using Muriatic acid I was able to bring it down to 7.5.
I'm only using bleach, Clorox (6%) and PurePower (regular scent), a brand sold in Giant Food Stores (Washington DC area) which I believe it is also at 6%.
What is causing the foam and how can I get rid of it?
Thanks for any help you can provide.
