OK I have a 250 G. acrylic. I dont have any overflows and I cant really move my tank out from the wall 8 inches to put a hang on overflow. I would love to have a wet/dry but I have 300 pounds of sand in the tank and my fish. It would be a nightmare to try to get the fish out and move the sand forward enough and dry the back corners to install the overflows. I have a chance to throw in the FX5. I have 2 XP3's right now. I dont really think they are enough filtration. Any ideas on what I can do to make this a better filtered tank? Should I attempt the wet/dry go for the FX5 or just stay with the 2 XP3's? Thanks for the help.
