The salt I use naturally has low dKH, I should have mentioned that. I'm not really open to changing my salt brand just because I have a full bucket right now.
I actually have been dosing Mg regularly as well (8 hours apart from the alk.), and its barely doing anything. I do have 2 mangrove plants in my sump, and I know they take up quite of Mg. You can see the rise in Mg the day after I dose.
I do 5g water changes ever week, and lately (in the last two weeks) have bumped it to 10g. Again because of the low dKH levels in my salt I feel its contributing to the problem.
These are the levels I got from freshly mixed up saltwater with RO/DI:
Red Sea Coral Pro Salt
SG 1.025
Mg 900
Ca 460-480ppm
dKH 6 or 2.2-2.6 meq/L
I'm afraid to stop dosing dKH for fear of it dropping below 4. What do you think would happen if I stop dosing? Would the levels continue to drop? I wouldn't mind stopping dosing, actually it would probably nice to do one less thing each day.
So if I understand, your recommendation is to work on raising my Mg levels, and in the mean time to stop dosing alk.
