Circular Flow in Cube Tank

[ddrueckh]

I have two Jebao WP-25 making circular flow in my 60 cube. Is circular flow in a cube tank good or bad? Will I get detritus build up in the center of the tank by doing this? Thanks for any tips or advice.

Depends on your rock pattern, how often you clean things out, your sump turnover rate (flow out of the tank), and how high the flow settings are on your pumps.

You're kind of limited to circular flow, if you think about it. It's either a vertical or horizontal circle. The exception is opposing powerheads. Generally chaotic flow is better but most vids of the sea show it "breathing" to and fro.

I have a Gyri130, sump return pump and two RW4's in my 2x2x2 cube.

Cubes are hard to master for water circulation, just try different mounting positions/directions till you're happy.
