Hi, I'm from Sheffield UK, I've been reading up on marine aquriums for about 4 or so years, I want to start up a a TMC 15L microhabitat. What I'm thinking of keeping in the tank is, 1 hermit crab, 1 pom pom crab, 1 narcissus snail, 3 or 5 sexy shrimp, 1 yellow clown goby and various zoas and shrooms. With the tank im planning on removing the skimmer and middle compartment and replacing them with live rock ruble in filter socks, a sand bed and about 2kg of live rock in the display side. I will put in a Tunze Mini Universal Pump - 5024.040 for extra flow in the tank. A weekly water change of 2L will be performed after the cycle is finished. I would most probably get a red sea marine test kit. Any other ideas on filtration or the tank? Any advice is welcome. Thanx.
