I could have written "Just buy a jebao RW", and I would not be wrong. That comment is based on water movement, controllability and price. Gyre is a very cool wavemaker, mine has been on my tank since they first became available, so 10 months? A year? I lost track, but its been running long enough for me to say, its fine, but about $150 too expensive for what it is. I am a reef veteran of 25 years and service local reef tanks as well. So I can say I regularly see all types of wave devices as well as their issues etc. Currently, my gyre control can no longer be programmed... for no reason. And a piece holding one side of the impeller guard just snapped off, with literally zero effort. It had that 5 year old submerged plastic feel that had lost its strength. Overall, gyre makes a nice flow, but I'm afraid it does not offer a reasonable value. And I won't buy any more of those for myself or my clients based on price vs quality.
