How fast can I raise ph

[Member No. 1]

Just did another ph test tonight it is 8.0. I ordered Red Sea marine care test kit today.

That's much better. Hold off on any changes until you can verify the results with the new test kit.
But if the results are the same, your pH is fine. 7.8 - 8.3. But don't get hung up chasing it. Just be sure your Ca, Alk, Mg are good, pH will take care of itself.

After a 50gal water change
Ph 8.2
Cal 420
Mag 1280
Alk 10
Will slowly raise mag corals are real pale. Another question I have is I have a duel reactor with phosban and carbon should I run it all the time or turn it off when phosphates are at 0
