Just wondering if there are ways to remover, if not all, most of the equipment that we typically see hanging on the sides of aquariums? I know you can do away with powerheads with at closed loop system, but most of the tanks I see with that setup have PVC pipes hanging down in them. I also know that your heaters and thermostats can be placed in the sump, but what else can we remove from the actual DT viewing area and what absolutely has to stay in there?
