Ph in a reef tank, how to raise it without messing up calcium, alk, and, magnesium parameters?

[Jeremy Lain]

Hello,

I have been learning about calcium, alkalinity, and magnesium in a reef tank, now I am learning about ph. What is a way to raise ph in a reef tank without messing up the other perameters: calcium, alkalinity, and magnesium?

Open a window in your home, to much Co2 can lower the pH that if its not to cold outside. Others are using soda ash used by divers to scrub Co2 you can add it before your skimmer air intake.

What is your current pH? It will be difficult to raise it without changing parameters in your tank - many of the chemical ways involve dosing calcium & alkalinity in a balanced way (kalkwasser topoff water, etc).

Opening a window near the tank would be a great test. If you do that for a day and notice the tank's pH increases then you know that you have stagnate air in your house and can think about ways to ventilate. I ran a tube through my wall to the outside and use that to get air for my skimmer which helps my tank's pH.

Running a refugium or algae reactor can also help, as plants will use CO2 as they grow.
