Is there something I'm missing when it comes to getting good flow out of these gyre pumps? I have a 90g display with two Icecap 4000s on a Hydros WaveEngine. I've previously had them at the opposite ends of the tank facing each other. The flow was... ok? They seemed to pummel anything that was down at about a 45 degree angle from them, but otherwise the flow was, not so great. I picked up some of the flow directors and have tried rotating the cages, but it doesn't seem to get much better.
I moved them to the back glass, opposite sides, just below my light mounts to see if it was better and I think it might actually be worse. Now it doesn't seem like anything is getting pummeled, but that's likely because it's pummeling the back of my rockscape where there aren't any coral. Ideally I'd like the flow to to be highest at the top, pushing across the top 6" or so of the water column where it hits the opposite glass and flows down. This is what videos seem to indicate they do really well, but I can't seem to get them there.
Any advice/suggestions? I'm happy to post some pics if it helps.
