Do you intend to keep corals? If so ditch the filter and just go for live rock you will need about 20 kg for a 4ft tank, and get at least 2 powerheads for circulation.
20kg for a 4ft? Try double that at least. I have 35 in my 200l which is less than 3ft.
. I've got one plant left because it's prickly so they can't get onto it, so going to have to fill the rest of the space with plastics.
. Nom nom nom!
