Finally pulled the trigger on the gyre to replace some my RW8 and RW4 and I am having issues. It is currently running at 60% in pulse mode with about 1 second bursts. It's in a 4 ft 75 gallon with some LPS and SPS. My rock work is set up so I have a large island and a small island not touching the front or back glass. The issue I am having is flow is perfect on the half of the tank where the gyre is horizontal placement 2" below the water line. The other half of the tank is a dead zone. In all the videos people where saying that flow was hitting the other end of their tanks at 30% mine only reaches about half way across unless I turn it up full power but then I get a noisy sand storm and my wall hammer and Duncan's are not happy no matter where I place them. Has anyone ever messed with the angle of the flow outlet? Shouldn't it be moving more water at 60%? It's definitely stronger when not in pulse mode but then I get sand storms. How is yours configured?
