Dosing Mg

Are you suggesting I should hold off? I sure would like to.

What gets me is my Mg was running at 1260 before I raised it to 1350, and then a month+ later it is back to 1260??

And I should add that my Ca and Alk have been stable all along with my dosing. Maybe I should leave the Mg alone?

No, suggesting I should get off my lazy ass and test my Mg

I've overdosed my Mg before and played around with it alot trying to combat bryopsis. I've also brought it up by way over 100ppm in a day. It's really not a big deal as if you were dosing Ca. Worrying just makes you lose sleep. Unrelated to you but on side note, I might add that this wont work on bryopsis thats just the Kent stuff.

Ok, I was inspired. Mg is ~1170pm. lol Almost perfect!!

I'm amazed you can balance the other two with mg so low. Maybe your kit sucks or it's diff for reactor folks?

I don't have to dose mg so long as I adjust my water changes to 1400. H2ocean is low. I add 160mL to 10g of new water.

Instead of dosing you could prob raise your water changes up some. What does your mix measure in at?

Ok so the rest of us following normal reefing parameters, like measuring ph, keeping magnesium at suggested proper level of 1350ppm, using something other than crappy old crushed coral in a reactor and our tanks are not half as nice as yours.......LOL....

Oh ya and chucking led,s.


Do you add a magnesium additive to the crushed coral or that level is what it maintains.

Ya, it's a low maintenance tank Nope, no additives, that's just where it sits. That's about where it was last year when I measured it.
To be honest, pre 2008, nobody even cared about Mg. Never saw it for sale or saw test kits. It's a recent requirement for tanks. I guess I have older corals, they don't care either -lol
