Yeah the airlifts will be tricky and I'll have really do my homework. The rbc's will work better than other filters with airlifts as they don't need a pump to run. Even though Summerfelt et al. suggest fbsf (fluidized bed sand filters) for salmonids, I don't like the idea of the extra utility cost to fluidize the sand. And I've heard the sand filters can be tricky.
