a good tank size to start off with
i have the same size tank but with a sump.
i would add 2 power heads
so 2 Koralia 1s
a skimmer deltec is very good try and get one from ebay
you will not need a filter. your live rock will be the filter.
but if u have the filter then you can put live rock rubble and carbon etc in it
are going to have corals? so a reef or a fish only?
you will need test kits. so ammonia,nitrate,nitrite,ph that will do until or if u get corals
you will need salt d&d salt is good
and a refractometer about £31 new http

remember take it slow. dont rush. also read and research as much as possible. i have spent so much on my tank but thats because i have brought every thing new.
