Magnesium magically stable (and high)

Wow. Maybe I'll stop mg dosing for awhile and see where the numbers go. I don't have any coralline as well but then I haven't seen much since I started the tank

What I've found is that my Mg never depleted very fast at all and always hovered around 1300 to 1400 with regular water changes. I tested often at first because I bought myself a fancy schmancy 4 head doser to take care of dosing Alk, Calc and Mag but the doser never got set up to dose Mg since my mag never depleted enough to warrant dosing. I do weekly water changes of 10% with the occasional missed week here and there. Or the occassional missed month like in December

LOL, sounds like my December

My mg does deplete but it does it fairly slowly. I find trying to keep it at 1350 for awhile there was difficult and then suddenly it shot up to 1500 for whatever reason. I do still have a feeling it will slowly decrease to about 1250 or something but it seems to hang around there and doesn't go lower. Not sure how closely its related to Alk like Ca is but my Alk levels are always in the toilet (5-6.4) and I never seem to be able to stay on target, I suppose because I have so many SPS in the tank.

I don't think your toilet's Alk level really affects your tank.. but I'm no expert on that matter. I will have to test mine to see what my toilet's alk level is at as now I'm curious..

well if it isn't etching the porcelain I wouldn't worry about it. I don't.
