I will also put my Tunze 6055 behind the rocks to provide flow in that area as well. That's about 8300 gph.

One thing to note, turnover calculations have changed since propeller-type powerheads have dominated the market. Since propeller powerheads provide gentler, wider flow patterns we can get much higher turnover than we could with impeller-type powerheads that provide a very direct, jet-like flow pattern.

It will be a mixed tank , I will have to ramp up flow as I add SPS later on.
