Achieve automated water clarity and high-capacity biological purification in a single compact unit with our range of combi drum filters. Combining micro-screen mechanical separation with an integrated moving-bed biological chamber, combi drum filters provide the ultimate all-in-one filtration solution for dedicated koi ponds and heavy bio-load aquatic systems.
Our collection features robust polypropylene combi drum units designed for both gravity-fed and pump-fed installations. Each system utilises an automated rotating drum fitted with stainless steel micro-screens to mechanically extract fish waste, uneaten food, and organic debris, automatically flushing waste away via integrated high-pressure spray bars before it can dissolve into toxic ammonia. Water then flows directly into the built-in biological chamber, where aerated media cultivates beneficial nitrifying bacteria to ensure stable water parameters with minimal routine maintenance. Explore our complete combi drum filters collection to upgrade your pond with builder-approved, automated filtration engineering designed for pristine water clarity and effortless fish keeping.
