Something smells humany
I have crushed coral substrate in my nano tank however I find that it traps muck a heck of alot and not exactly the kindest substrate to burrowing fish and stuff SO...would I be able to take out all the substrate in the tank without hurting the cycle of the tank etc... because my idea is to get more crushed coral and crush it even finer so it's more like a sand... so it buff's the PH level up but is better for burrowing crustaceans
