any ideas on wot you are going to stock

fish only ??
live rock

as depending on wot you plan to stock depends on wot equipment you require
but generally you will need some sort ov filter a heater , skimmer , can you fit a
sump ?? or will it be cannister filter ?? for equipment reading reveiws is always a good idea ,
just because its a good brand doesnt mean to say its a good product ,
lighting is a big issue depending on your stock ,
