6105's?

[km1das]

Alright, I'm sure you hate these questions but I'm setting up a 180 that's 72x27 footprint. I'm not sure how many of what powerhead to do, 4 6105's, 6155's? It's just confusing and I don't know what the full size turbelles are like. Any help is appreciated. Thanks.

In general, 2 6105's is what I would use for a 180, this should suffice for all but the highest flow SPS tanks or tanks with very dense rock structures. If I was to add anything to this it would be a Wavebox, adding the wave to the tidal flow pattern of the 6105's is really the ideal and would allow you to keep just about anything happy.
