Hi everyone-

This is my first summer where my wife and I own an in-ground concrete pool. Loving it so far, after finally getting the water good and learning the ins and outs of maintenance (Thank you very much to TFP and the extensive backlog of forum posts!)

I have a random, potentially simple question for my first post. I have one extra bottle of 12.5% liquid bleach that I don't need to put in anymore, and hopefully won't have to for a little while if I got the CYA stabilizer and chlorine pucks working right. That being said, I heard the higher % liq bleach bottles lose potency past. If I picked this one up on Monday 6/10, about how long until it would be no longer that useful pouring into my pool?
