I recently had a algae problem that this forum helped me resolve. Thank you. I went to the pool store today to buy my polyquat 60 and the pool person suggested I use "No More Problems". I believe the bottle listed sodium bromide as the ingredient. The pool employee told me that "polyquat 60 was formulated by companies on the west coast for west coast algae. Living in South Florida we have different trees and algae problems." I was reading the bottle but the instructions were vague. The pool store guy told me to "just give it a good squirt once a week".
Needless to say I bought the Polyquat 60. I couldn't get home fast enough to post my experience and get the opinion of the true and unbiased professionals.
