The guy at the pool store said Algae Destroyer by (Nature's Way) was what we needed when we asked for polyquat algaecide. (I looked at "Pool School" thread Winterizing above ground pools.) Is this what I should use. It has poly (oxyethylene (dimethyliminio) ethylene(dimethyliminio) ethylene dichloride) 60% and other ingredients 40%.
Thanks!
