Well for my nano im going for an aquac remora skimmer, one question, could i get the 55 gallon model instead of the 20 gallon model and turn off the 55 gallon model at night and turn it on during the day? I want good skimming but skimmers can be loud and the tank is in my room. There only 30 dollars difference in price and i do plan on getting a 55 gallon reef tank one day anyway
