Dolomite?

I know that Marine Depot used to sell it, but they don't seem to carry it anymore. I thought that there was a crystalline form of it for your reactor, but all I see online are powders. Check with JB to see what he used. I know his came in a can and I think he said he just dumped the whole can in.

In any case, the powder stuff should be found in the fertilizer/supplement section at your local lawn and garden/farm supply store. Also, it's used as a supplement as well so if you don't have luck there, check your local GNC or nutrition store. Look for the stuff that says Phosphorus free as some of it will have phosphates present. Good luck.

He's used dolomite in his since day 1 and in conversations with him, it's worked well. I recommended to talk to him more to see what vendor he got his dolomite from, than to see how it's worked for him.
