Quick question about wavemakers, timers and powerheads.

As for fish it will be a jawfish, some clowns, orange spotted diamond goby, later on a blue mandarin goby and maybe some other stuff if I am not overloading my tank. As for the corals I don't really have a good idea of what I would put in there. This is my first salt tank so I am still rather new at this.
