Flow in cube? Harder than I thought

[mrhasan]

One RW-04 doesn't seem to do anything in my punyaquarium (15"x15"x15"). Got this one on the back at full blast and detritus still settles in places where I don't want to be. Seems like getting the flow right in cube is not that easy or maybe I am missing something.

Thinking of adding another RW-04 on the other side; any advise? Thanks

Ive got 2 rw8s and an mp25 in a 120 and its not enough , I know the flow is wide but I don't think they put out as much as they advertise.

I think so too. Marketing after all

Have you played around with different flow settings? I find so many people get obsessed with the "wave" settings, but forget that the other modes are probably better at stirring up detritus.

Also, if you're going to have these on the back, I'd suggest having one on either side.

Yap I did try other modes but the dead spot at remains there directly below the power head. And the rock makes it worse. Here's a picture to show the location of the PU. The dead spot appears to be around the mag cleaner at the bottom left corner at the back of the tank. The flow pushes everyone to that corner and that spot reminds me of Jurassic Park I (the pile of poop lol).

I have the same problem in a biocube but I went to put my mp on the left side of my tank seem to split the rocks better

Tried that but didn't make any difference in my case. Added another RW04 today. Fishes are surfing with the flow now.
