Chem Geek -

Forgot to mention, that we had been using the Slime Bag for a while early on. When we were using sequestrants and got the pool clear/green, then I tried to bring CL level up 'slowly' at that point and went right back to opaque brown.

I also used the Slime Bag to filter our fill water along with a hose pre filter (put Slime Bag over both), then filled a bucket and poured bleach in the bucket - turned brown.
