Maintaining a Good pH

Ok, My question is about pH. Is there a way to maintain a good pH around 8.2-8.4 or do you have to constantly keep checking the water and add pH increaser's or on the other hand pH reduction products ?

Thank You

 

I've found if you keep you alkalinity up it helps.
Good salt mix helps. Some have low pH I have found.
A refugium with a reverse daylight setup (light on after display light goes off) keeps the pH up.
A properly setup calcium reactor would help - although I had a big one on a 20 long once and it actually brought the pH down I think. Nevermind this - I am being confusing.
Aragonite sand may help too.

 

Make sure your calcium, magnesium and alkalinity are at least as high as natural seawater. That should help. You may need to dose your change water to get them up to NSW levels. You can do calcium and magnesium at the same time but will need to do alkalinity a few hours later or as part of your dosing regime.

 

Fresh air to lower the CO2 levels and proper dkh levels . To see if its CO2 that is causing the problem ake glas or bowl of tank water outside and bubble it with a air stone and pump then for a hr then check the PH
