magnesium uptake in sps tank

[Coleus]

I think the magnemsum depletion rate in your tank depends on your setup. Mine for example, before i have lots of mangroves which consume lots of Mg , so now i took them out and the depletion rate has been dramatically decrease. The best way is bring your Mg to the desired level and then measure again in a day or week then you know how much Mg is consuming by your tank.

Good luck

I am thinking using some of these when I have to refill calcium reactor. at the mean time probably keep on dosing.

so, plants/macro algae uses more magnesium than coral then??

thanks

I've been running my sps tank for a year and a half and I've dumped about 100 lbs of magnesium into the tank. That seems like a lot to me. I run zeomag in my calcium reactor along with ARM? I don't know why. This is just from experience. I use Littlesilvermax's Mg mix.

I agree, I have to dose a lot of it to keep up with the demand. I even try to keep the coraline algae to a minimum because it can be a big sink for mag.
