Sorry if I was inactive, but I posted this thread for equipment. Currently the tank has: 1x Aqua-tech 20-40 hang back filter 1x Aqua-tech Regent Powerhead 1x Tetra submersible heater 10-30 1x already-used Aquatech 30-60 (I am aware that used equipment could be faulty) 1x glass thermometer ALL aforementioned equipment was bought new except the 30-60 hang back filter. Is my equipment appropriate for my future 29 gallon reef? If not, what are some alternative equipment? What other equipment do I need? I want a protein skimmer and I probably want a sump too,but it is in my shed and is bigger than the 29g.
