Got it. It's cal hypo + STPP + Magnesium sulfate (why?)
Full info below.
If that's all you've been using, you've got no stabilizer in the pool. If you've got bleach at home, dump it in the pool tonight.
Get some stabilizer tomorrow -- but you can NOT let it touch those tabs. Bad things WILL happen.
Does your pool have a skimmer, or are you using a floater with the tabs?
