  • ACCEL AQUATICS BIOPELLET AND FILTER MEDIA REACTOR - FR-30

    The Accel Aquatics Biopellet Reactor is specifically designed to fluidize biopellet filter media without the need of a strong or high flowing water pump. The special penductor or "flow accelerator" located inside of the reactor produces very turbulent and strong water movement inside of the reactor. This keeps the biopellets suspended and moving which is critical for biopellets to function properly. The inverted conical bottom helps even further by preventing media from clumping and settling on the bottom of the reactor. The reactor does require a separate water pump for proper operation to pu... [Read More]
