That should improve when you get the Alk and Mag up. I tried a different salt for a while (instead of RS Coral pro), that really dropped the Mag and Alk down, and as a follow up the Ph. I quite quickly got the Alk back up, but the Ph was still too low (7.9). In the last two weeks, I have managed to get both Alk and Mag up to correct levels, with a combination of dosing and water changes, and the Ph is now back automatically where it should be (8.2-8.4).
Have you got a dosing pump, or do you dose manually? I Dose manually for Calc and Mag, but use dosing pump for Alk.
All of the above is of course for the RSM250.
