This was tested around 10 pm and my Specific Gravity
is between 1.022 and 1.023
That is pretty low for a true reef tank.
Bump it up slowly to at least 1.025...
Natural sea water has specific gravity 1.026!

p.s. My recomendation is not about your pH problem,
but to make your future reef animals happy.
