I am starting to get together a 57 gal Amazon Cardinal Tetra tank. Since this is a slow water planted biotope I am concerned that the 2217 at close to 300 gph may be too much? The 2215 comes in at around 200 gph. I am going to split the return and come through 1" bulkheads in an effort to reduce turbulence. Any ideas?
