Flow around rocks.

Attached is a picture of the rock. It seems that there is not as much flow in the corners and I worry about behind some of the rock. I have 2 tunze 6045s in the tank currently. Thoughts?

I have a 180 with two of those overflows. I used some 3" PVC street wye's glued together with enough of a length of straight pipe to wrap around the bottom of the overflow chambers. I also drilled a number of 1" holes in the assembly. I then placed a Tunze 6025 at the opening to provide the flow I needed around the base of the overflow chamber, and between the rocks. It also creates a nice place(cave) for the fish to hide.

Here's the idea:

Rock work covers the pipe, so you can't see it.

That is probably the most ingeniuous idea ive seen yet

1) bigger pumps...your tank dwarfs the 6045's...think about moving to some 6095's
2) put your live rock on a diet, could lose a couple of pieces....

Why not lower your power heads if flow around the base of your rocks is a concern.you could also put them on your back wall for an over all more turbulent flow.
I have a 210 with 2 mp 40s on the sides facing each other and 2 more on the back wall facing the front wall.this with being a bare bottom tank gets me pretty good flow

Also +1 on the dude saying lose some rock
