How many powerheads.

[ltkenbo]

So I currently have a 55 gallon and I've got 1 Koralia 2 powerhead, some small cheap powerhead and I've got a sump which generates a lot of flow also. So I was planning on getting a couple of more koralias. How many more should I get to have proper flow. I have some very small soft corals right now and once I upgrade my lighting system this Christmas I'm planning on getting many more corals hard and soft.

To help you figure out what type of flow would need here is a picture of my tank:

Sow how many more do you think?

I have the same tank with a K2 on one side and a K3 on the ohter, plus the sump return, Ithink I have plenty. The two Korillas are on either end of the tank facing each other, but one points down and left, the other up and right sop the flow rasses each other. The K3 has no problem blowing the water all the way down the tank from the side.
