RW15 on 60gal Cube

[Doug]

I use two 8,s on my 3ft. 50g. If I crank them up its almost to much. I run them and a pair of MP40,s just to get a variety of wave action. Mine were from Reef Supply also.

I've got two rw-8 in my 120 and they seem to provide plenty of flow. I would do one rw-8 or two rw-4.
