hey guys, im gonna be getting a 125/150 for my africans soon, within the next month or two. Right now on my 46 i have a fluval 405 and a Pengiun 350b (50 gal) filter. Id prefer to leave them on that tank and start over with filtration for the new tank. What would be the best ideal for filtration besides a sump, as im not too interested in drilling/plumbing/etc etc.
