Cloudy Water

[lauramor]

Hello everyone,

My pool looks good from outside but when I open my eyes underwater is very cloudy and I can barely see. We are listing our house for sale soon and I am afraid my water may turn green when we have buyers coming to look at it. We cleaned the pump filters today and they were not too bad. I did an overnight loss test and it was 0.5. Here are some more numbers:

FC: 5.5
CC: 0
CYA: 30. I have been wanting to raise this a little and I had chlorine pucks leftover from the previous owner so I have been putting some pucks in the water to raise CYA. I am afraid I will get yelled at for doing this.
TA: 80
Ph: 7.8
CH: I haven't tested because I live in AZ and I expect high CH.

What could be the cause of the cloudy water? Thank you so much!

Cloudy water is about 99% of the time algae.
Raise your FC to SLAM level. Maintain it.
Once you pass, raise the CYA to 50 ppm. You can use the pucks if you like, just discontinue them when CYA gets to 50.
Do not rely on the pucks to add enough chlorine. Not likely to work.

Thank you! I will start the SLAM process tonight. Is it safe to use the pool while slamming?

Sure. As long as you can see the bottom of the pool in the deep end.
