Calcium sulfate percipitation

[madkeenreefer]

I have done a bit of reading and belive that in the attmpt to raise my MAG from 1260 to 1350-1400 (over a period of 12 days) I have managed to achive percipitation.
Q is how do I remove this from the tank or will it eventualy disolve if I stop dosing my 2part MAg by the way its a mix at 2-5.

I also run a Cal reactor and top off with Wages for Kalk. both 24/7.

I don't think you're seeing calcium sulfate precipitation. Calcium sulfate should dissolve well enough into saltwater. Whatever the precipitation is, it'll likely disappear on its own.

Where do you see a precipitate? In the tank or in the bottle?

The precipitate when mixing clear magnesium chloride and clear magnesium sulfate is likely calcium sulfate, and that will redissolve in the tank.

The precipitate when adding the alk part of a two part is magnesium hydroxide, which does redissolve in the tank.

I discuss it here:

from it:


Figure 3. The transient cloud of magnesium hydroxide that forms when high pH additives are added. In this case, the alkalinity portion of B-ionic was added to a fairly still portion of one of my reef aquaria.

Thanks for your time guys I have read the link just befor to post last night and kinda realized that I had already answered my Q but appreciate the imput and reasurances applied.

MR. Holmes-Farley I also found your write up on http://reefkeeping.com/issues/2006-07/rhf/index.php useful aswell.
