Helix Bio-Mechanical Waterfall Filter

The unit includes the necessary Helix biological media (15 liters for the small, 50 liters for the large). However, you will need to purchase the mechanical media separately, which requires 35 lbs for the small model or 100 lbs for the large model of 3/4" lava rock.

It is designed for easy maintenance. You can clean the filter externally without disassembling the unit, and it is specifically engineered to be cleaned using pond water, which helps preserve the beneficial bacteria colony.

The filter features a heavy-duty, roto-molded body that is designed to be easily concealed within your landscaping. Its durable construction allows it to blend into the surrounding environment while remaining accessible for maintenance.

By using lava rock without restrictive mesh bags, you maximize the biological surface area and maintain higher flow rates. This design prevents clogging and ensures water flows efficiently through the media, which is critical for effective filtration.

Yes, while the filter includes the necessary hardware for an air-assisted cleaning cycle, the air pump itself is sold separately. This cycle is an optional feature that helps agitate the media for a more thorough clean.

The small unit is designed for ponds between 1,000 and 2,000 gallons, while the large unit is suitable for ponds between 3,000 and 4,000 gallons. Both models support a maximum flow rate of 4,000 gallons per hour.
