I have a 72 AG bow front fowlr tank that I'm rebuilding rite now.. I'm using a filstar xp4 for this build.. I read on the Internet it's rated for aquariums up to 250gallons... and I was thinking since its a smaller aquarium that I could do a custom plumbing setup in the aquarium. Most of the plumbing will be hidden by rock and sand.. I want to try to plumb atleast four lock line returns randomly in the tank. Hoping this will also eliminate the use of power heads in the tank.. I'm prob gonna beef up the drain a bit too.. But my main concern is will this be to much for the filter/pump in the xp4? Any thoughts???
