I just picked up a customer that is fighting pink "algae" in his pool. Hundreds of dollars have already been wasted trying to treat this pool using conventional pool store wisdom. He had been shocking the pool almost daily with dichlor and trichlor, so the CYA was up to 100. He has been burning through chlorine tablets extremely fast. He said he had to refill his chlorinator daily, and he had two floaters in the pool, yet he still couldn't get the chlorine to stay in the pool.
So I added liquid chlorine to bring the FC up to about 60, and I'm going to keep it up there until it passes an OCLT.
Today I read something about pink "algae" and it talked about Sodium Bromide, and said that using Sodium Bromide would eat up a lot of chlorine. Is this true? Could it be that the Sodium Bromide is causing the difficulty with maintaining FC in this pool?
In any case, I think my best course of action is to continue to SLAM and brush the pool.
