No fancy equipment at all. No sump, fuge, or skimmer. I have 2 HOB filters and 2 powerheads. One filter has carbon and one has LR rubble. For some reason this tank has worked out very well. My plan in the beginning was just a fish only tank then it slowly grew into reef set up. You should try the same thing with your 33g. Maybe take it slow like I did, add frags over time until you have all you want. If you want any more info just let me know.
