I've got a problem with a very low Alk, around 4-5 dKH that I'm having trouble raising. I'm dosing the BRS 2-part system but when I see it dosing the Alk mix into the sump, besides the white cloud, I see flakes throughout the sump. I'm guessing this is precipitation, and if so, how do I dose the Alk mix w/o this problem? Should I dump my current batch of Alk and make a new batch and dose that or is there another problem i'm not aware of.
