how old is this tank?I have a 10 gallon with a 100 watt mercury vapor light over, here is a new picture of it since the rescape. It has home brew CO2 and EI dosing. I went with five white cloud mountain minnows, some microsword, some local hairgrass, and I have some blyxa japonica to fill in the back right corner. Substrate is a blasting sand called "Black Beauty" which seems to be identical to Tahitian Moon sand. Hardscape is a piece of local shale and two pieces of garnet-laced Adirondack granite.
