hey guys, I am setting up a malwi mbuna tank and the tank is pretty close to being cycled. I was planning on keeping 15-18 mbunas in my 55 gallon tank. I already have a 350gph tetra power filter and a 150gph tetra power filter. I am planning on buying a xp2 for the tank wich has 300gph. would this be enough filteration for these fish?
