I just got a 44 gallon pentagon aquarium for a saltwater setup with live rock and coral but first I need to get a filter. The only problem is that it has to hang on the side due to its location in my house. I would prefer it to be quiet and not splash but cost is a factor and well beggars cant be choosers. I have looked into the HOT Magnum and the Aquaclear power filter, but really dont know what to get. PLease help.
