Ok....I just called my hydro guy....that's what I do when I want THE REAL SCOOP. You may NOT use H202 with Hydroguard so most likely that is what happened. As for hygrozyme he says you CAN use H202 with it......but that it is the only "ZYME" product you can use with peroxide.

The ingedients in the hydroguard are bacillus (bacteria) I think you committed mass bacill-icide and discovered the corpses post mortem.

MURDERER!!!!!!
