Synergy Combi 25

Advanced All-in-One Pond Filtration System with Integrated Mechanical and Biological Filtration for Medium-Sized Ponds

Synergy Combi 25

The Synergy Combi 25 is a premium compact pond filtration system designed to provide both ultra-efficient mechanical and biological filtration in a single unit, ideal for ponds up to 5,500 gallons. Engineered to deliver crystal-clear water and maintain a healthy aquatic ecosystem, it combines an automated drum filter with a biochamber to remove debris and promote beneficial bacteria growth. The water level is designed to match the Nexus 220 for easy integration, making it suitable for hobbyist and semi-professional ponds.

Equipped with a fully automated Siemens LOGO control panel, the Synergy Combi 25 ensures precise management of cleaning cycles while reducing manual maintenance. Dry-run protection and a 210Nm direct-drive motor guarantee durability, while the 70-micron drum screen with integrated Blanketweed and debris trap efficiently captures solids. The biochamber, aerated by a built-in air stone, holds 135 litres and comes with 50 litres of Hel-X media (expandable to 100 litres) to support optimal biological filtration. The filter can continue operating even if the motor fails, providing consistent water quality at all times.

Compact yet powerful, the Synergy Combi 25 is ideal for koi and ornamental ponds requiring high-performance filtration with minimal intervention. Its innovative design, automated drum cleaning, and integrated biochamber simplify pond maintenance while delivering reliable water clarity and ecosystem stability.
