Re: Algae is Back
OK, I got the Taylor K-1106 phosphate kit. The pool water is indeed high, around 800 ppb. I tested 3 times... once diluted, twice non-diluted, and results were consistent. However, the tap water is zero... no hint of blue whatsoever in two non-diluted tests. So, I'm not sure what the source of the high phosphate would have been.
In any case, I have now ordered the Kem-Tek 265-6 phosphate remover and I'll begin dosing after I receive it.
FYI, I've been maintaining FC at 20+ for the last 5 weeks, and this is with relatively low CYA of 32. Daily consumption averages around 3 ppm. After brushing, the algae returns to the same spot about 2-3 days later, without fail. Here are the rest of my current numbers:
FC=20.5
CC=0
pH=7.7
TA=75
CYA=32
CH=260
Borates=50
Thanks again,
Mike
