Welcome. IMO a canister is more trouble in the long run than it is worth, but it depends on what your goals are for the tank.
Some type of surface skimming to a sump/fuge would be better, even if you are just wanting a few fish. More rock before anymore livestock for sure.
Luckily thee are plenty here that will chime with lots of knowledge and experiance to guide you along. BTW, looks good so far.
what is SFE?
