Well I am using an "Aqua 65" from Superfish, the internal volume actually works out at around 60 Litres. It has internal fitration with bio-tubes and heater. I have added an internal "Maxi-skim" protein skimmer which I shall turn on when I have fish or inverts in there later in the cycle.
I have a nice thick bed of TMC Coral Sand and am going to get about 5KG of live rock i reckon.
