enough flow??

you could try a "gyre" Which is like directing your flow so it moves all the water in a whirlpool style pattern around the perimeter of the tank. I use it in my 55g tank with one Korallia 4

thx, thats kinda how it is right now I't a 1/4 round tank, so the flow scoots nicely across the curved front.

i have 2x koralia 3's in my 40g breeder and my fish LOVE it. that would put me around 2000 gph of flow in my tank including my return pump.
