Hi Carmen,
cloudiness is usually caused by the beginnings of an algae bloom.
The other reasons is for calcium precipitation or addition of some of the pool store snake oils.
In one of your posts, you report hardness (which is calcium) as 154 and then again at 1000. Thats just not possible as you have to add calcium for it to go up.
anyways....
Most lilely the cloudiness is due to algae, but hard to cofirm that without a proper test kit.
However, the cure, is to kill the algae with chlorine and filter the dead algae out of the pool.
