cloudy water bromine pool

[chem geek]

A bromine pool doesn't normally need or use Cyanuric Acid (CYA). I just re-read your other thread where you explained this is indeed a bromine pool. I wouldn't worry about the CYA level. Are you able to hold a bromine level -- that is, it doesn't drop rapidly during the day?

Have you tried shocking the pool by adding chlorinating liquid or bleach? Even with a bromine pool, that would end up raising the bromine level and would do so quickly before getting degraded by sunlight, though generally it's a good idea to shock at night so you get the full overnight at a high sanitizer/oxidizer level. If what is making the pool cloudy is something like dead algae, then it can go away by higher levels of chlorine or bromine. Look at the Best Guess CYA Chart:

though with your low CYA shocking to 10-12 ppm Free Chlorine (FC) which is roughly 20-25 ppm Bromine would be something to try. Remember that you need to retest and add more to keep the level high. From the other thread it sounds like you are going to be replacing the liner and then can convert to chlorine. That will make things a bit easier.

Do you have any idea what caused the cloudiness? Did it just get slowly cloudy or did some specific event happen?
