Okay, I added 4 gallons of bleach (6%-generic brand) and 4 pounds of borax (easy to find at super target). Waiting and watching and definitely happy with the tiny dent in my wallet from this pool shopping excursion!

BTW, I am running my polaris to help circulate it all. Is that a bad idea, good idea, doesn't matter?

I'll test again in a little while.

Another question, does it help or hurt to have the automatic cover closed. I have 5 little kids so I tend to leave it locked all the time unless we are in the pool. Is that part of the problem? Does the poor ol pool just need some sun?
