I have been reading this forum and found good info but i'm to the point that i need help
its a 10,000 indoor pool, pool only gets light from skylights (needs heated in the summer still)
I moved in and the pool was fine, I checked the level weekly and put one 3inch clorine tab in the pool and all was well.
about 1.5 months after we moved We had a party, lots of kids, I increased the Clorin from 3 to 6 on the colrinator before the party. the pool was a little cloudy for about 2 days and cleared up fine
we have been using the pool and I when to take the cover off to use it again (had been about a week) and it was cloudy.
From reading here i bought a Taylor kit
FC = 2.5
CC = 2.5
CH = 400
TA = 200
PH = 7.7 (also used my digital meter for this)
CYA = ??? we could not get a reading the tube was perfectly clear all the way through? tried the test 2 times
temp = 88
i used http://www.poolcalculator.com/ and got 0.73 witch is what i got with the test kit.
I Think it needs shocked, but i don't want to waste chemicals until i know about the CYA
also the TA seems really high
we use well water to fill the pool witch lucky comes out 7.2 - 7.5 ph LOL but it is hard water and Iron heavy.
i would not mind the BBB but i just bought clorine tabs and pool-perfect off amazon and shock.... witch i can't return.
