PH/Alk Plan of attack

[CarlD]

I must disagree.

Your pH is WAY out of control. Bad enough to cause all sorts of problem. Add acid to lower it into the mid 7's (7.3-7.8) It MAY bounce around a bit, but it probably won't.

Meanwhile, don't stop shocking your water just yet. I would keep my chlorine at shock levels until it is PERFECTLY clear. Just because CC is 0 doesn't mean you cannot get another outbreak. It just means that at the moment, algae is dead but you aren't "there" yet. Now is the time for patience.

When pH and chlorine are under control, THEN you can add baking soda. I would start with 1 lb, not 6. Then wait 24 hours, check T/A again, and add another pound. Keep doing this until your reach 100ppm. You can add more, but you don't want to go over your target. THE TRICK TO MOST CHEMICALS IS TO GO SLOW! THIS IS ESPECIALLY TRUE for pH adjustments.
