What do you use for flow?

[Delphinus]

75g (48x18x20) - 4xMJ12 on wavemaker, one in each corner, left side and right sides are together and pointed at each other to get the "back and forth" effect.

110g (30x30x30) - 2xStream6100 on multicontroller, left and right, alternating to the "back and forth" effect. Plus a serious amount of flow from the sump return (I don't recommend this approach at all, don't make your sump return a main source of water flow in the tank).

In my opinion, cube tanks suck to get a good flow pattern happening because there just isn't enough length of tank to get a good wash going. For every drop (so to speak) of water that goes one way, there's a drop going the other way.

I'm going to be moving my streams into my 280g if/when that ever happens, in which case I'll either change the cube into a Seio on a Wavysea waving back and forth to get the "back and forth" effect. Or I might just put two 802 powerheads on a wavemaker.

Or I might just tear the tank down, I haven't quite decided what I want to do with it yet.

40g (24x24x12), 4 powerheads (2 MJ12, 2 Hagen 301's), on wavemakers plus SCWD on sump return. Not too bad of an alternating pattern but again kind of hard to get a really good pattern going on account of the weird shape of the tank.
