Mp60, I think is too much. I am running 4 Mp40s on my 260 and its a crap ton of flow. The mp40s will move around 5 feet of water effectively. Here is what I like a dislike about the 3 I would use on an sps tank
Tunze,
Controllable
Moderately Priced
Lots of Issues with death of the pumps
Flow is a steam almost linear in comparison to the outlet of the pump
Great Customer service, but doesnt go very far if your having to continuously having to return pumps
Korallia
Controllable
Cheap in price
Wide cone shaped flow stream
They tend to run in reverse and break fairly easily, but I guess you get what you pay for.
Vortech,
Wide stream
Controllable- but in a more random different way then the others
No Cords in the tank.
Very low energy consumption(not sure on how they rank compared to the others above though)
Expensive.
Ecotech are very proud of their product, and are very very Arogant. Are not the cheapest things in the world to repair.
I wouldnt trade them for the world though.
