Finally, a high-quality and affordable Rotary Drum Filter (RDF)! These RDFs will strip even the tiniest micro-debris (down to 120  microns) right out of the water column before it even gets to your biological filter.

How Do These Work So Well?

Dirty water enters the filter and is screened through a rotating drum filter (RDF) which physically separates dirt and debris down to 120 microns from the water column and then automatically flushes it away! Yes! You heard correctly, 120 Microns! even the best-designed Sieves on the market can only filter down to 200 Microns, so this is almost triple the filtering power of even the best sieve. The reason it can filter out this small of particles is because of the automatic rinse that occurs. Typically this occurs several times a day automatically which prevents the screen from getting clogged. In a normal pond, it's not realistic to clean a filter several times a day which is why these can work so well.
