I set up a new 10' x 30" Intex pool a couple weeks ago and have been using the super simple recipe for Intex pool maintenance from your wonderful site. My shipment of dichlor shock hasn't come yet, so I've just been using bleach so far. My pH level has been remaining steady at 7.8-7.9, so I haven't had to add any borax yet. I was wondering if I should use some muriatic acid to bring my pH level down to the 7.2-7.6 range, or if I should just leave it alone? Also, what is the shelf life of shock? I'm hoping any I have left over from my order will stay good until next summer.
