I would not wait for your PB to balance otherwise you may end up with a rough surface or deposits. This can happen when the PH and Alk are too high.

So I would get the PH and Alk in line as soon as possible. I kept mine around PH 7.2 and alk 80 to keep some of the dust in solution to more easily filter it out. This reduces the dependency a bit on brushing.

Also, chlorine will help keep the algae out so I would do that right away too.
