Flow in a frag system?

Hey guys. I have been debating between two powerheads for a while. The CoralVue High Seas 201B High Output DUAL Propeller Driven PowerHead, 1,500gph, 12W OR the CoralVue High Seas 202B High Output DUAL Propeller Driven PowerHead, 3,000 gph, 24W.

Here are the links to both of them.

CoralVue High Seas 201B High Output DUAL Propeller Driven PowerHead, 1,500 gph, 12W - AquaCave

CoralVue High Seas 202B High Output DUAL Propeller Driven PowerHead, 3,000 gph, 24W - AquaCave

I want quite a bit of flow in this tank. It is a 125 gallon long tank with a mag18 return which is the majority of my flow right now. There are also 2 other koralia 900 powerheads in the tank. I currently have them aligned like this...



Forgive the poorly drawn paint art. : The arrows are the direction in which the flow is pointed. Hopefully this is enough information. Ive been thinking about this alot. If I add the 3000gph powerhead Id like to take one of the 900gph koralias out and use it on another tank. Any input is greatly appreciated. Thanks in advance!

 

Bump.

 

Seems pretty good to me.

 

You mean with the 3000gph powerhead?
