First....thanks Ben, that's alot of cool info!

I have my liner in with fresh water so I started with the 6% bleach..... Clorox regular brand 2.97 at wallymart. I put 1.5 gals in and had a middle of the road level a few hours later. Two days later with tons of rain it was zero....so I have to test more often and get the hang of how much and how often. My PH was at 7.0 so I picked up some borax today.....4 pound box. How much should I start with? And how do I put it into the pool? Can this go thru the skimmer or broadcast? This won't stain my liner right?

Thanks
Cooper
