Solar Fish??

according to the manufactures info it is harmless to filters and people and compatible with all forms of sanitizers (CL, BR, Bac), ionizers, etc. It HAS been in use for quite a while now and if there were negative effects I'm sure we would have heard about them. The main thing about it is the question of whether it is a cost effective and just darn plain effective solution to heat loss and evaporation.

Um, I don't mean to be snotty here, but manufacturers of pool chemicals try EVERYTHING to convince people the methods advocated on this forum are crazy.

HTH, one of the biggest chem companies, recently reformulated their Tri-Chor tabs to include copper, which generally VERY bad for pools with the advert "Now double-acting!"

CarlD,
I mean that if there are any negative effect I am sure that someone in this forum would have pointed them out to us!
