I sent my wife to the pool store to get polyquat algaecide and they sold her this stuff call Sea/Gard Winter Chemical and told her this is the best stuff for winter instead of polyquat. It has 3.5% Copper Dulfate and 2.5% N-Alkyl Dimethyl Benzyl Ammonium Chloride and .01% Dialkyl Methlyl Benzyl Ammonium Chloride.
Stupidly, I put it in the pool without checking or asking.
Am I ok with this? Presumably, I don't need to also add algaecide.
Thanks in advance for any comments or suggestions
