I'm sure this is a completely stupid question, but, who else can I ask? We still have gallons of "Poly-Guard Ultra Shock" leftover from when we first opened our pool last month. (Before we found out about BBB.) The ingredient list says:
Available Chlorine: 15%
Sodium Hypochlorite: 12.5%
Inert Ingredients: 87.5%
Sooo, is this stabilized or unstabilized chlorine? We don't want to use this stuff if it's going to add any more stabilizer to our pool. CYA isn't mentioned anywhere on the label, but we're not sure if it's part of that vague "inert ingredients" description. Thanks for your help!
