Happy July 4th everyone and I hope you're enjoying your pools.
I'm using the TF100 tests while SLAMming and still failing the OCLT (FC drop overnight was 2.0) but the CC remains at 0.5. Is this possible or am I doing something wrong?
Had SWG issues, so pool was green when opened a few months ago. I treated with bleach until water was clear, but cloudiness kept coming back in the deep end despite more shocking and last week I noticed algae settling in the seams/deep end when the pump shut off. Bought the TF100 test kit last week, initial test results: FC 5.5, CC 0.5, PH 7.2, CYA 50, TA 150, CH 200, Salt 3000, and started SLAMming 5 days ago. Overdid the bleach at first even though I used the pool calculator (shouldn't have added 5 jugs in one day) and brought the FC level up to 28.5 instead of 20.0 (CYA=50, PH=7.2), I brushed and ran the Polaris cleaner during this time and added some DE. Pool was clear but two days later, I turn the Polaris off to let things settle and I see dead/while algae buildup in the seams, which was fine and what looks like dirt but was probably algae in the deep end and what looks like sand in some places on the steps (pool is around trees but no sand). We vacumn the pool to waste till we can see no more and keep testing.
The FC keeps dropping overnight by 2.0, pool still clear,and I notice what looks like a little more algae accumulation in some of the seams, not much, but still suprising especially given the high FC level. We have had a lot of rainfall the past two days, probably about 2 inches last night. This morning, the OCLT dropped by 2.5 (average of two tests) but the CC remained at 0.5 which was similar to past OCLT tests this past week. It just doesn't seem like it should take this long since there wasn't that much too start with, any thoughts? I'm also wondering if the sand stuff was the start of Mustard algae. This morning tests showed the FC dropped by 2.5 down to 16.0 (will add another jug of bleach today) and pool still looks clear. I might shut the pump off for a few hours and see if algae or anything else accumulates. Any help would be great, thanks.
