I upgraded my gyre blades about two weeks ago. I was amazed at the difference. I initially had it running at 58%. After the upgrade I had to turn it down to 30%. I have two trachs on the sand below the gyre and it was sucking up so much water it was moving them around.
Yeah I'm wondering if I have mine cranking too much flow. (If there's such a thing?) I'm at full power but have it on pulse so it's not constant.. I'm debating changing the blade combination and run it sideways. But I finally have it running good I don't really want to mess with it too much. I run bare bottom so I don't have the issues like that anymore..
