      Hi Aswin...since I haven't used that particular media, I can't comment as to its efficacy. It looks similar to K1 and other manufactured plastic media but that's as much as I can say. I used K1 because the manufacturers stipulate the amount of feed that a given quantity of media will accommodate. Can you approach the supplier for more information?

        What about incorporating a fluidized sand bed after static bed instead of a k1 moving bed (Preferably a mini form of "Cyclo Bio Reactor", Designed by marine biotech.inc, which needs less pressure to get fluidized and is designed in such a way that the sand will get a cyclonic movement along with lift & have a provision to remove heavily loaded sand from top )

          12000-liter Fish tank having bio-filter running on Airlift pump at approximate 15000 LPH. No need of water pump...airlift pump alone will serve several functions... 1.aeration 2.circulation 3.degassing 4.foam removal 5.no electric lines in water 6.no moving parts 7.harmless to baby fishes And 5 times energy efficient than water pump in low head applications...Easy to run on solar systems... The biofilter is being coated with biofilm...This filter will keep the Water clear and in good quality...

            gary..same as your design but water pump is replaced with airlift pump...

              Aswin...if you can achieve the same water flow at the same (or less) energy use, then it might be a proposition...for all of the other benefits that it provides. Since I haven't used an airlift in this design, this is purely my opinion and is not supported by experience.

                Aswin...this device looks as though it would be quite expensive compared to a moving bed biofilter. I do know that most fluidised sand filters require adjustments to the pumping pressure as they load up with solids.
