New flow idea

[Quinster]

I am doing hidden design on my new 180G, I will be running a Reef Flo Dart and an OM 4 Way...here are the design pics;

Top View

The center 1" return (in the overflow) will be from my sump, going to a T and then to elbows pointing straight down behind the rockwork.

What do you guys think about blasting water straight up behind the rockwork on lets say a 24" tank front to back? Do you think the water rolling towards the front of the tank and downwards would be strong enough?

Jaws,
I have a 180 that has one hole drilled in the bottom pane of each of the front corners about 6" from the edge of the glass I had the flow runing straight up from a dart on a CL didnt notice a whole lots of back to front movement but I do also have two returns from the CL exausting toward the front of the tank disrupting that flow. I did however just add some OM omniflow jets http://www.oceansmotions.com/store/p...b83d4d148f926e and directed the flow toward the back corner on each side now fish are using it as a treadmill

Quinster are you using two 2" intakes for the CL on a dart IMHO you would only need one 2" (Factory recomended to take 2" inlet) or even a 1 1/2". Might save you the cost of an extra hole and weakening the tank.
PS I have a 1 1/2" intake on a dart and the pumps are shipped with a 2"-->1 1/2" adaptor

Have you watched my videos? Shooting the water straight up to the surface gives AWESOME random turbulance!
I have always thought that if you need to use motorized flow devices, you either don't have enough flow in your tank, or don't have it positioned properly...

You can never get perfect flow IMO always tweaking to get it better. Then stuff grows.

With my 6000 gph coming out of a 2.5 PVC pipe it would shoot water right out of my 250 gallon tank if I had it pointing straight up. I run the flow along the bottom of the tank, and even then it wants to spill over!

Could have some flow pointed that way though, wouldn't hurt.

thats definitly the knew way of thinking. Im trying something knew with a sinsuidal valve and undergravel plumbing

the reason for the 2 2" is less chance of sucking some un suspecting fish or invert into the line, also to take water from different areas to allow for more random flow.
