Looking for flow ideas

[lastlight]

not saying this is helpful but what I do with minimal powerheads is a gyre with some pulsing flow across it.

I have 2 x 6105 stacked on top of each other and about 5" off my sandbed blastic across the back of the tank... aimed slightly upwards to keep some sand in place. then you can see where I have my other 6105s on the back wall. they flow across to the front through gaps in the scape... but they are still angled so when they hit the front their flow direction is with the gyre. All 4 of those switch up on the interval 2 setting on my 7095.

I added a pair of tiny 6025s to fill in some deadish spots. They actually made a difference!
