pH still reading 6.8 after "pH Up" and one hour of circulation. I added 1.5# of Borax to the skimmer, with pump/filter on "bypass to pool" which I presume is circulate.

I bought algaecide for black algae (which I don't have, but), it was the only one I could find that says poly-something-something-ethylene 60%. I diluted that and added it to the pool, just in case - I don't need to add to my list of problems.

I'm gonna let those 2 circulate for an hour or so.

Still on the fence about shocking vs. adding another bottle of sequestrant. The bleach/pool water concoction was still yellow and had a brown tint to it. It was such a long, expensive road to get from opaque brown to clear-ish green, I think I'd rather fight chlorine levels than metal levels. Even 50 gallons of bleach will cost less than $140 (which is what the sequestrants have cost me so far)

Once I do shock, I know I have to do it slower than those blessed with healthy water. Never having used the BBB method (because I've never owned a pool before this season), how much liquid beach over how much time is 'slow'? And do I bypass to pool (circulate it) or filter it?
