Just started TFPC on Oct 4. SLAMed for a week or so-- pool was greenish when we began--- pool was looking sparkling by Oct 10 and down to 0 CC by Oct 20, good levels, etc.
Well, now it is Oct 30.
Yesterday we noticed a faint cloudiness-- stll can see to the bottom easily, but just not "sparkling". Husband scrubbed the whole pool we were within normal FC.
Today there is a small yellow patch, maybe the size of a dnner plate. So-- mustard algae is back? We scrubbed 2x a day-- extra on the ladder, light, and drain. Could this be because our bottom drain is stupidly plumbed and doesnt work, so it's staying in there where we can't get to it? If so-- why did it stay sparkling for weeks?
Also-- is pH supposed to rise quickly? Nothing went into the pool the last 5 days and yet the pH was 7.2 on Oct 24, 7.4 on Oct 26, 7.8 on Oct. 30.
We filled it 1 inch with hose water Oct 25. Hose water does have high ph-- 8.0, but still it was just an inch.
CYA- 70 (bringing down slowly
I'm going to start SLAMing now, but I am confused by the pH--- oh--- and my FC was 6 on Oct 24 and it's still at 5 almost a week later???
And why is this mustard algae back again? We were so vigilant and followed every rule of SLAMing!
It's 75 degrees here. (60s at night)
