We've had the new pool up since Saturday now and I've added some bleach, some Borax, some Arm and Hammer, and some CYA, according to what I've read on this fine forum, so now, of course, the weather has turned to...well, you know. I was wondering when it was going to turn from weeks of unseasonably warm weather to the coldest/wetest summer on record as a direct result of us putting in a pool!

So the rainy days are in the 40s and nights in the 30s here in Denver and the cover has been on for 2 days, do I really have to be that on top of the chlorine? There won't be humans in this bag of water till it's waaaaaaaaay warmer. When does algae begin to grow? This being our very first year with a pool, I don't even know when people around here open a pool. When do you really need to begin playing around with the chlorine/ph/alkalinity etc?

Thanks.
