Starting a new tank

Back at the start of September I decided it would be a great idea to get another fish tank, by the start of October I finally got my 3ft x 2ft x 2ft tank delivered, I decided to go a high tech tank this time just for something different, (Much to my wife's dismay). So here is what I got in the end

3ft x 2ft x 2ft tank with sump
Rubber 3D back ground
60kg of Gravel (mixed with Laterite for fertilizer)
Hydor Under gravel heater
AquaMedic 1000 Co2 Reactor
PH/ORP Monitor with Co2 dosing
UV Sterilizer
Awesome piece of drift wood with a hollow all the way through
