First pool in my life. Water came from city fire department. Put in 8 ounces of HTH shock, waited 8 hours and tested. High chlorine, high CYA, high TA and high pH. Waited 24 hours and tested again. Same results. Pool store told me I need to lower the pH with pH Minus. Put half the bottle in. New test results by HTH 6-way test strips:
FC - 1
pH - 8.4
TA - 180
Total Hardness - 400
CYA - 30-50
Water at the current moment is crystal clear and beautiful. Except when you look down at the bottom of the pool, there is this brown stuff scattered all over the bottom like dirt or sand would look if you just threw handfuls in the pool. When I disturb this stuff by stirring the water or getting in and moving my feet through it, it turns into "clouds" of brown and then the pool water is murky brown.
I have put pantyhose over my skimmer basket and over the flow outlet (pushing water back into the pool) and am changing them daily because they become ugly dark dark brown silt. I have rinsed my pump filter out daily as it turns solid brown.
The pool is covered with the debris cover when I'm not swimming and re-covered when I get out. It sits in the direct sunlight all afternoon with partial shade in the morning.
I think that's it. Please ask if you need more. Thanks.
