I run a Jeboa DCT-4000 return at 100% in my RSR 250. My wavemaker is a Gyre, Glamorca GP-03. You may be able to compare the specs of this with the ReefWave 25. Both do the job for me. Having only 1 Gyre mounted on the left does mean I get dead spots on the left, particularly at the back. Some prefer two, mounted on the back facing forward.
