High Flow Rotating Powerhead Diffuser

[downhillbiker]

Does anyone know of a rotating diffuser such as the Hydor FLO, but for higher flows. I have some pumps that are rated like 800 gph and the Hydor FLO is only rated up to 300 gph.

I have heard people who use the Hydor FLO for higher than recommended flows wear it out in a matter of a couple months.

I am looking for either one I can buy, or build, either one.
