Yea, pretty much just a heater and that powerhead. I also had an eclipse 12gal biowheel filter on there, but biowheels are a nitrate factory for a reef setup. I took out the biowheel, but left the filter pad and just changed that out regularly. The key is doing consistent water changes, 25% per week, and have good amounts of LR for the nitrification cycle.
You could also look into setting up a refugium, either in your sump if you have one, or a HOB fuge.
