Can i ask for your opinion of the gyre thingy mate, noise compared to Tunze pumps and is the flow as good as they say ?
Really happy with The Gyre, this one is the XF 130
I used to run tunze 6055 and 6095 on controllers.
The water flow is IMO way better than a stream pump. Stream pumps are directional and point source.
The gyre can shift water in a big way. Having a gyre wave is a lot more gentle and yet moves more water.
The Gyre is great as continuous and ramping faster and slower.
In forward motion it scores five stars however in reverse gyre I give it zero out of five stars. I have not changed a paddle over to trick the flow in my tank to running a forward / reverse gyre simultaneously.
As for noise you can't hear it.
Had to switch off everything and have the gyre on 7/10 to hear it.
I would say that of the two gyre I have heard, on XF 150 at the LFS
And My XF 130 these units make a fraction more noise than Tunzes. But not noticeably
I don't think that noise will be a complaint from users.
