As much as I would like it, we can't magically clear up pool water: the chlorine you'd already added did it WHILE you were posting here. With OTO 'brown', that's pretty much what I already expected.

+ Go ahead and keep it orange to orange-yellow for 1 day AFTER you have CAREFULLY brushed the whole pool.
+ Run your filter 24/7 at the lowest speed, or most restricted flow rate you can manage.
+ Your pH readings are NOT trustworthy when your chlorine is that high.
