Ilex Biodrum Rotator 45 is our top model among the Ilex Biodrum filters! This model is a major upgrade over a standard Biodrum. The moving bed has been replaced here by a Rotating Biological Drum (RBC). The RBC is standard filled with Helix as a Bio-Media. This can also be filled with other biological material if desired.

The RBC is a rotating trickle / drip filter concept that requires no lift height from the pump! The RBC is 40% under water, and 60% above water for maximum oxygen saturation. The big secret of this design is that oxygen can be found in up to 4% * in water and 20% in air. This gives the pond bacteria the best conditions to perform their work efficiently.

The rotating movement of the RBC ensures that a trickle / drop filter is created without a lift height. The industrial motor of 250nM of 60 watts turns the RBC.

Ammonia and nitrite removal:

Scientific studies in fish farming have shown that an RBC guarantees a very high ammonia and nitrite removal, 50% better than trickle filters and much better than moving bed / mat filters!

Benefits:

• Better biological effect
• No more lift height compared to a trickle filter
• 2x as efficient as a moving bed / mat filters
• Faster start-up than a moving bed / mat filters
• No cooling in winter compared to trickle filters
• No noise
• More stable bacterial culture with use of medication and changing water values
• No need for an air pump anymore
• Water is of better quality
• You can feed more
