Rotating Drum Filtration and Mesh

Dirty water enters the unit and passes straight into the rotating drum filter, where a patented woven 75/120 micron stainless steel mesh captures solids before they ever reach your biological media. Once particles build up, the drum spins and the system flushes them out on its own.
-
Drum diameter of 40 cm x 50 cm for high solids-handling surface area
-
Removable spraybar for quick access and simple cleaning, fitted with a row of red and white quick-release nozzle fittings
- Driven by a 50 NM engine at 4 RPM for steady, controlled rotation
-
Installed cleaning pump running at 5 Bar to blast debris off the mesh
-
1 x 110 mm waste outlet plus a removable waste water gutter, with waste cleaning available as an option
Two 90 mm drum bypass ports keep water moving even during heavy loads, so your pond never goes short on flow.
Biological Polishing With the Sea Side Aquatics C35M Moving Bed Filter
After the mechanical stage, water flows into a fluidized bed of media that keeps helix constantly tumbling. Powered by air, this stage adds oxygen while feeding the beneficial bacteria that break down dissolved waste.
-
Moving bed capacity for 200 liter helix
- Separate mat chamber holding 300 litres for extra filtration surface
-
2 built-in air discs of 35 cm drive the fluidized action and oxygenate the water
The result is water that stays healthy for your fish and stable for your whole ecosystem.
Automatic Control Panel and Operation

Set it up and let it run. The plug and play sensor triggers automatic cleaning the moment it detects buildup, so you never have to guess when maintenance is due.
-
Manual run/wash option when you want direct control, with a dedicated manual cleaning button and a red on/off rotary switch right on the panel
-
Adjustable cleaning time for turn and flushing cycles
-
Adjustable cleaning level to match your pond load
-
3 plugs giving you command over the drum filter motor, cleaning pump, and pond pump, plus a separate sensor socket
-
Standard dry run protection that guards your pond pump
