Drum Filters

Drum filters for koi and large ponds

A drum filter is a self-cleaning mechanical filter. Water flows through a fine mesh screen on a rotating drum. When the screen loads up with waste, the drum turns and spray jets rinse the debris to waste, automatically.

Why koi keepers choose drum filters

• Fine filtration: removes small particles that ordinary foams let through.
• Less maintenance: no manual foam cleaning.
• Better biology: removing waste early reduces the load on your biological stage, helping keep ammonia and nitrite low.

Planning a drum filter system

Drum filters are usually the first stage in a larger system, followed by a biological stage and a UVC clarifier. They can be gravity-fed from bottom drains or pump-fed, and need a drain point for wastewater. They suit koi ponds, large ponds and swim ponds.
