My husband and I opened our pool about 3 weeks ago. We never covered it, and the pool was swamp green.
Long story short, the pH got WAY to high (hot pink). There is a rough sand paper substance (I assume calcium scaling) on the sides of our vinyl pool (and probably the bottom too, not sure..can't see down there ).
I brought the pH down to 7.2 before I began shocking.
Good news is that the algae is dead. We did an overnight test last night, and we only lost .5ppm.
Bad news is that the water is REALLY cloudy still (after 3 weeks of keeping it as close to 16ppm (shock level) as possible).
I really don't feel it is algae causing the cloudy water, since we only lost .5ppm overnight.
We thought it might have been our sand filter, so yesterday, we opened it up, and coiled a water house down into it very gently. The sand was soft, it was NOT compacted, so we now feel the filter isn't the problem.
I now assume the cloudiness is from the calcium that is falling off the walls as we brush. Is there anything we can do/buy to clear the calcium from the water?
We've spent about 200 dollars on bleach the last 3 weeks. It's been rough, but I am trying to be as patient as possible.
One other option I've thought of, is partially draining the pool. I had to do that about 3 years ago when our CYA level reached 100+. I can't remember though how far we can safely drain a vinyl pool without hurting the liner.
We are at a loss, and don't know what else to do.
Clarifier? Calcium sequestrant (which I can't find anywhere online), partial drain??
Oh, and we don't use calcium hypochlorite, we use 6% bleach, so I am not sure why our calcium would be that high (unless bleach also adds calcium to the water).
Let me know what you feel I should do.
OH, and here are my current test results:
CYA - 40
FC - 12
CC - 0
TC - 12
Ph - didn't test it since FC is over 10
Alk - 100 (it was 120 yesterday, so we added 27 oz of muriatic acid..hope that wasn't a mistake)
CH - 120 (very hard to tell...lot's of little things floating around during the test)
Thank you for any help/advice you all can provide!
