Ok so I have a canister filter coming to replace the two HOB's on my 55g. The canister comes with plumbing and a single outlet return for the tank. I was going to make a spray bar and wanted some opinions where I should place the spray bar. Should I put the inlet on one side of the tank and the return(spray bar) on the other side to make a nice current throughout the tank or make a big spray bar and hang it on the back firing towards the front? FYI the tank has 4 large angels, a handful or rams, small shoal of serpae tetra and a couple smaller pleco's.(BN and gold nugget). Any help would be appreciated. I'm pretty new to canisters for aquariums.
