Cool How do I position these stupid things?

I picked up two Koralia #3 circulating pumps for additional flow in the tank which should bring up my flow to about 2400 gph which should be enough, however they don't indicate the best positioning for these critters. Can someone give some insight on how to best position these things. The tank in question is a fresh start up 120 FOWLR. Thanx all.

It will vary on your rock arrangement, but a decent starting point would be to place the flow intersecting in a V at the front.

Put the pumps upper rear extreme (left/right) and position them in a downward position toward the front center of the tank? What exactly is this doing for my tank?

It's mainly trial and error. Every tank has a different set of rockwork so the pump has to be positioned so you have as few dead spots as possible. That V position with the two pumps in back facing front and center sort of hits the two currents from the two Koralias togetherto form a chaotic and random flow pattern.

The intention is to have as much circulation through the rocks as possible?

Yes and no. You don't want constant flow directly at a rock or nothing will ever be able to attach. Some corals like higher flow, some like lower. The object (at least AFAIK) is to create a random pattern to somewhat immitate the way flow would be coming over a reef in nature. You obviously don't want any completely dead spots either.

I have mine so that the flow basically skims the top of the rocks closest to them and the flows meet in a V at the front glass. Like TC said, it's mostly trial and error.

Thanx HN1, Now that I have a better understanding it is much clearer on what i have to do. I like the magnet thing it makes them easy to adjust.

Only if the rockwork allows it.

I would suggest placing into an imaginary "x" in the aquarium angled towards the surface.
