Bromine Chemistry Question

[FormerBromineUser]

A2. ...Use borax to gradually raise your pH to 7.8, while continuing to chlorinate. Once your pH is 7.8, begin adding 1/2 lb doses of calcium hypochlorite DIRECTLY to your skimmer, while the pump is on. This 'shocks' the water in the line upstream of the filter, and tends to drop iron out ON your filter. Continuing to use DE during this process will also help pick up remaining iron. Make sure your pump is on 24/7

Okay, just to make sure I have this correct. I am supposed to lower my pH to 7.4-7.6 with MA after I do the above.

1.) Doses above is plural and I am pretty literal... How many doses of cal-hypo in a day? I have been doing one and so far I have not yet had to backwash.

2.) How long should I wait after adding dose(s) before adding the MA?
