Where do I get dolomite Tropical Fish Keeping

2012-6-28  Whether or not an aquarist needs dolomite depends upon the source water we use (tap water normally) and the intended fish. And here I'm thinking freshwater fish. Some fish occur in very soft water, the hardness (which is primarily determined by the minerals calcium and magnesium) can be near-zero, and the pH is usually on the acidic side.

Dolomite is safe as substrate? is this dolomite? 3reef

2013-5-15  Dolomite should be fine. Here in the US some use approximately 10% dolomite (products like Zeovit's Zeo-Mag and Brightwell's NeoMag) and 90% aragonite in the calcium reactors because the dolomite is virtually the same as aragonite with a higher concentration of Magnesium. Using it for substrate should be perfectly fine.
