Hi,
Just wondering are you intending on FOWLR or Reef tank?
As for whether these are enough, have you got the other equipments such as Protein Skimmer, Powerhead, Chiller/fan, Live Rocks and maybe test kit?
You may need some live rocks to have start your cycling.
In case you have not read the excellent article o for beginners, may I recommend it to you. It should be pinned on top of this section.
Cheers
