Tunze Powerhead Locations

[Aquattro]

I use scenario A. I have 2 6100's going across the back behind the rock that create a wave. I have 2 smaller pumps (6055s) in front blowing end to end about mid height.

I have 4 6015s in a 400 and they currently meet all my flow needs. What I do is:

- 2 on rear pane, bottom left blowing straight across the back. they are as close to the sand as possible. this create a nice continuous gyre.

- other 2 are on back wall midway up the rear pane blowing towards the front but slightly angled so as to not work against the gyre.

This is working really well so far.

Thanks for the input! Greatly appreciated.
