I'm planning in planting a 55 gal tank 48" long. I have a fluval 306 and 405. Will that be too much for this tank? I want it to be medium to heavily planted with a large school small school some corys and a centre piece. If that's not too much filtration, I have an issue. The 405 won't fit under my stand, well it will but won't lol. Can I just buy a 305 base and use that since its shorter?
