Coral Essentials 2 part with trace elements

[mxnutz]

Hey all,

This is my first time using the CE 2 part with trace elements and after dosing the carbonate portion of the bottle first. There are small white looking snow particles forming as it being dosed into the sump. I believe it is precipitating out of solution. I know that if I dose part A and then part B relative close to each order. The solution will precipitate. But in this instance, I haven't dosed the calcium portion yet. I run a kalk reactor in my sump and thought it might be the kalk reacting with the carbonate solution but I have another tank that doesn't run any kalk and dosed 2ml of the carbonate into the sump and it is doing the same thing.

I have used ATI essentials, B-ionic, ME Corals 2 part in the past and this is the first time seeing it. Is it because of the trace elements in the bottles or something else I'm missing?

I have emailed Rick and while I wait for his response. I would like to hear what you guys think...

Thanks in advance.

It is normal to get transient precipitation of magnesium hydroxide when you add high pH additives. It will redissolve if you mix it in rapidly, before it has a chance to sit around and form the more slow-forming but more problematic calcium carbonate.

This is normal:

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.

This is the first time I've seen it form so quickly in my 16+ years of reefing. Looked like someone threw rice in my sump. haha...

I'll move the output to a spot where the carbonate can mix faster and spread out the dose more during the day.

Thanks Randy!
