So the title kind of says it all... I have a 90 reef tank that is mostly zoas, euphyllia and soft corals. I have a MP60QD that I run, but I am wanting to try something different or even just run both of the pumps on the 90...? I also like the top movement of the water with the gyres, but I was wondering what your guys opinions on them is and what brand you prefer more than the other? I'm thinking that if I get one and like it on the 90 I might get one for my 20 high mixed reef also.
