I got the pool running about 3 weeks ago. The only chemicals I had to add (starting with fresh, brand new tap water due to a new liner) were bleach and a little muratic acid to bring the PH down slightly. I also added one bottle of Leslie's stabilizer which brought my CYA up to around 30ppm.

I have two boys (8 and 10) who have been the only ones swimming, with an occasional friend. They have probably swam (word?) 5 times in the last two weeks. I have kept an eye on things after I got readings where I was happy, adding bleach when FC started to come down. I have had crystal clear water until this point.

Yesterday, I came home from work and the water was cloudy. My wife says it was clear when they took cover off, then became cloudy after boys got out of pool. It had been a while since I added some bleach, so without testing, I just added a gallon.

This morning, water is still cloudy. I can see bottom drain cover in deep end, but it is not clear by any means. I tested the water and here is what I got:

FC = 6.5
CC = 0.5
PH = 7.4
AK = 70
CYA = 30

After reading some other posts on cloudy water, I am thinking 1 gallon of bleach was not enough to "shock" the pool...is this correct? I can't imagine I am at the beginnings of an algae bloom already...air temp has been around 80 the last week or so, no rain, pool temp started 3 weeks ago around 68 and has gradually crept up every day and is sitting around 82.

The pool is in ground, 12x24, with about a 7 foot deep end, approx. 10,000 gallons. Has vinyl liner. Has cartridge filter.

Thoughts?
