230 gallon system
pH 7.98
SG 1.025
Temp 78
PO4 .03
NO3 .5
Cal 440
Mg 1275 (down from 1320 4 days ago)
ALK 7.4 (down from 7.5 4 days ago)
Auto-water change with Reef Crystals has been off for 5 days. Restarting tonight.
Would like to run ALK at 8.5-8.7 and Mg at 1350-1375.
Will dosing saturated Kalk raise both of these or only the ALK (and pH)?
Do I need to brink ALK up with sodium bicarbonate first and then maintain with Kalk?
If not via Kalk, how do I raise the Mg level?
Thank you
