I have a 48” 75 gallon tank (not set up yet) that I bought 2 Aquaclear 50s for. However, I just realized they won’t fit over the rim of the aquarium. From what I’m reading, an Aquaclear 110 will. It is my understanding that once you hit 48”+ in tank length, it is ideal to have 2 filters (one for each end), vs 1 to most adequately filter the tank. What do the experts in here think? One 110 should be enough for this tank, but should I look for another brand so that I can have 2 filters?
