emerald crab, I have a 180g display tank. With about 40g of water in my sump, I have 150lbs of live rock in my display, so usually when I dose I do so for 160g of actual water.

I am using the Fluval Carbon, I buy it in the 1650g container, the lable is stateing it's a low-ash carbon, and I consider it to be a fine granual with the pieces being in the 3mm range.
