Choosing the Right Drum Filter: A Deep Dive into Burtons BD-300, C30, and Minima Combi Units

 

For koi enthusiasts, water quality isn't just important—it's everything. A pristine pond doesn’t happen by luck; it requires a combination of the right equipment, good maintenance practices, and smart investment in filtration. At Beacon Koi Ltd, we proudly offer top-tier filtration technology including the Burtons BD-300 Combi Pond Filter with Socket Panel, Burtons Pond Drum Filter, C30 Combi Units, and the ultra-compact Minima Combi Unit.

These advanced systems are designed for various pond sizes and koi populations, and they provide crystal-clear water with minimal maintenance. If you're setting up a new pond or looking to upgrade your current filtration system, this guide will help you understand the features, differences, and benefits of these powerful pond filtration units.

Why Drum Filtration Is the Gold Standard

Traditional filters often fall short when it comes to handling large debris or maintaining long-term clarity, especially in koi ponds with heavy bio-loads. That’s where drum filters shine.

Burtons drum filters, known for their efficiency and innovation, automatically remove waste from the water before it enters the biological stage. This not only keeps water clearer but also extends the lifespan of your bio media and cuts down on maintenance.

Burtons BD-300 Combi Pond Filter with Socket Panel

The Burtons BD-300 Combi Pond Filter is a powerhouse designed for large koi ponds requiring high flow rates and maximum filtration. The integrated socket panel allows for easy connection of UV systems, air pumps, and other pond accessories, offering full control and automation in one unit.

Key Features:

Automatic self-cleaning drum with 70-micron screen

Integrated bio chamber with static K+ media

Electrical socket panel for seamless device integration

Ideal for gravity-fed systems on medium to large ponds (up to 65,000L)

This model is especially popular among koi professionals and hobbyists with high-stocked ponds. Its automation and capacity mean less hands-on maintenance and more time enjoying your pond.

Burtons Pond Drum Filter: Efficient Mechanical Filtration

The Burtons Pond Drum Filter (standalone) is ideal if you already have a separate biological filter or if you’re customizing your own filtration chain.

Benefits of Using the Burtons Drum Filter Alone:

Captures solid waste before it reaches bio-media

Simplifies maintenance with auto-cleaning cycles

Compatible with both gravity and pump-fed systems

Reduces organic waste and boosts overall water clarity

Whether upgrading an old filter or starting a modular build, the standalone drum filter is an excellent first step toward a clear, healthy pond.

C30 Combi Units: Compact Power for Medium Ponds

If you want something powerful but not as large as the BD-300, the C30 Combi Unit is a fantastic option for mid-sized ponds.

Why Choose the C30 Combi Unit?

Combines mechanical and biological filtration in a space-saving unit

Supports ponds up to approx. 30,000L

Easy installation for both pump-fed and gravity-fed configurations

This unit is a favorite among hobbyists who want high efficiency without the footprint of a larger unit. Its compact design does not compromise on performance, and it integrates well into most garden pond setups.

Minima Combi Unit: Small Footprint, Big Performance

For koi keepers working with limited space or smaller water volumes, the Minima Combi Unit delivers an excellent balance of filtration and convenience.

Minima Highlights:

Ultra-compact size ideal for small koi ponds or QT systems

Includes drum filter and bio section

Works with lower flow rates while maintaining efficiency

Great for mobile pond setups or budget-conscious builds

Even with its minimal size, the Minima doesn’t cut corners. You still get the reliability and design quality Burtons is known for, in a sleek, affordable unit.
