I like to buy in quantity in order to keep the price down (and I don't run out as often!). Online I found a 25# bucket of MPS (potassium monopersulfate) which I use for shock.
Anyone know if this stuff has a shelf life? At the rate I use it, 25 lbs. would last a
lonnngggg [/u]time! I'm only using a few ounces once or twice a week.
Might even be a lifetime supply. Or I could pass it out as Christmas presents to friends with hot tubs or pools...The choices are endless...
Is there a shelf life?
