| Turnover rate is the key
Just to confirm what has already been said, FIR or no FIR, turning over the pond volume 1 1/2 - 2 times per hour is the key to an effective shower no matter what type of media is utilized. Most other types of filtration systems rely on solids removal through multiple stages of physical filtration before much bio action takes place. Shower trays literally seek to pulverize and completely digest solids rather than remove and discard them so a higher flowrate is essential.
