Yeah I have learned that in a folr tank a hob
skimmer is okay but if you want to do coral you will want a sump with a protien skimmer placed in it. Just a heads up you will spend money because you will fid yourself needing other things likely an auto top off. I have heard that you should not use a canister filter because the will house nitrates and it could cause a problem. You will find that LR
and your protien skimmer in the sump should be sufficient I recommend you get a sump large enough to have a refugium built into it or one that comes with a refugium but if you are pinched for space they make hob
refugium just make sure your tank is a minimum of 5 in from the wall or you will kick your self later like me. I have to have my refugium custom made because my tank can't be moved. Live and learn. A refugium is Danm near a necessity from my research.
