hi,
i've just started using my new tfp test kit, along with the pool calulator. everything's been going good til now. we have algae spots, about 15 were scrubbed off yesterday. water looks clear and sparkly though.
here are my numbers:
FC 3.5
CC 0
TA 110
ph 8.2 (adding m.a.)
ch 250
cya 50
borates 80 (can't explain how this happened, added less than it was supposed to take to get it to 50)
salt 2850
i also tested with the tester for chlorine with the ph tester/it said 5, but when i tested with the other, it was only 3.5, but it didn't show any cc.
if i understand correctly, i need to shock to 29 fc, how long do i maintain this level? i will continue brushing also.
any ideas what is off on my numbers that let the algae come in?
thanks for any advice in advance.
