Dinoflagellates - How to Raise PH

[Werbo]

Airation is not a problem in my tank with a large skimmer and 2 MP40's causing lots of surface agitation.

I will look for the Aquavitro - Balance.

Sunday morning parameters:

PH = 8.07 (8.31 at lights out last night)
Salinity - 1.024 (down from 1.026)
Alkalinity - up to 8.8 dKH (8.0 yesterday)
Ca/Mg didn't measure today

Any other suggestions?
