D Ponds Bio Filter 02 (DPBF02)
DPBF02 is suited to fluidized or moving bed tank systems. DPBF02 can support about 35 lbs of fish per 2 cubic feet of media, where fishes are fed 1.5% of their body weight per day. A safer measure is a maximum of 0.55 lb of food per 2 cubic feet used, in order to ensure the best possible water parameters are achieved.
How It Works
DPBF02 media provides the maximum active surface area for the bacteria to colonize, more than other types of static media. It is this process which removes harmful ammonia and nitrite from the water. As the DPBF02 media moves within the filter, it causes the old dead bacteria on the outside to be displaced. This makes space for younger, heavier feeding bacteria to rapidly colonize. Within the wheel is a protected surface, which enables colonies of bacteria to naturally follow their life-cycle of maturing, dying and then fueling the latter stages of the nitrification cycle.
Unlike foam, matting, or other forms of static filtration media, the DPBF02 media is designed to move freely within your filter. The constant chaotic movement of the air causes the media to self-clean and thus requires no maintenance. This allows the filter to reach optimum effectiveness without the disturbance of periodic cleaning, avoiding unnecessary loss of bacteria within the filter.
