I've been through pool school, bought the test kit, and thought i mastered it but still have algae creeping around.
FC 5.5
CC 0
TC 5.5
TA 140 (little high)
CYA 60
Ph 7.5
12k pool vinyl liner
i had the CYA issue at but turned my dark green swamp with live tadpoles into clear swimmable pool after about a week but now after keeping my free chlorine up to around 3-4 for the last month and its been fine. Last weekend, I noticed a touch of algae near the stairs and around the bottom edge near one of the jets - brushed it away and tested my levels and everything looked fine.
However,, I hadnt been brushing like i should - could that be the problem? I did empty the cartridge filter after the shocking process and it was gross/white and hosed it all out.
Today, I took my cartridge filter out and it was medium? green from algae. Could it possible that in the filter, algae somehow got in there and spreads to the pool even with high enough FC?.
Also, my FC drops very quickly - i feel like i have to put more in like 5 gallons a week minimum to keep my FC at 5? Does that seem to high? I've tested my CYA like 5 times to make sure i'm doing it right - the black dot test and it comes in at 55-65. Maybe thats too high? PoolCalculator says 7 is my target FC so maybe i just need to get it there and keep it there.
Any thoughts to my ramble?
