Superior Koi Health With the Sea Side Aquatics BK60 Moving Bed Bio Chamber

Struggling to keep your koi pond clean and toxin-free? Waste and ammonia build up fast, and your fish pay the price. The BK60 puts an army of beneficial bacteria to work on constantly tumbling media, breaking down harmful toxins before they ever threaten your fish. The result is clearer, healthier water your koi will love, backed by biological filtration that keeps performing day after day.

• Bacteria Colonization: Tumbling media creates a large surface for beneficial bacteria to break down ammonia and waste.
• Water Quality: Continuous biological filtration keeps water clean and clear for koi health.
• Media Capacity: Holds 100 liters of moving bed media (media not included).
• Air Diffuser: 12.5"D disc drives media circulation and adds oxygen to the water.
• Air Inlet: 3/4" connection for an air pump (air pump sold separately).
• Flexible Use: Integrates directly into an RDF filter or runs standalone for biological filtration.
• Flow Rate: Handles up to 9,000 GPH for larger koi ponds.
• Plumbing: (3) 4" inlets/outlets for straightforward, high-volume setup.
• Dimensions: 36"H x 22.5"L x 22.5"W.

How the Moving Bed Design Powers Cleaner Water

The magic happens in the movement. Media pieces circulate freely inside the chamber, giving beneficial bacteria an enormous surface area to colonize. As the media tumbles, old biofilm sloughs off and fresh colonies grow, keeping the bacteria active and hungry.

• Constant motion keeps media clean and bacteria thriving
• Massive colonization surface for breaking down ammonia and waste
• Holds 100 liters of moving bed media (media not included)

The chamber accepts your choice of moving bed media, so you can fill it to suit your pond's biological load.

Inside the Moving Bed Chamber

Look inside and you can see exactly how the BK60 keeps everything working together. Retention screens on two walls hold the media in place while water flows through freely. Grey air distribution pipework routes air through the chamber to the bottom, where a 12.5" air diffuser disc pumps a steady stream of bubbles up through the chamber, driving the media into constant motion.

• Media retention screens keep the moving bed contained
• Grey air distribution pipework delivers air down to the diffuser disc
• 12.5"D air diffuser disc circulates media and oxygenates the water
• 3/4" air inlet connects to your air pump (sold separately)

Pair the Sea Side Aquatics BK60 Biofilter With an RDF for Complete Filtration

Mechanical and biological filtration make the perfect team. Drop the BK60 into an RDF filter setup and you get the best of both worlds. The RDF handles the physical waste while the BK60 tackles the dissolved toxins that mechanical filters leave behind.

• Designed to integrate directly into an RDF filter
• Complements mechanical filtration with strong biological performance
• Also works standalone when you need biological filtration on its own

Built to Handle Serious Flow in the Sea Side Aquatics BK60 Pond Filter

Big ponds need big flow, and the BK60 keeps up. With a maximum flow rate of 9,000 GPH, this chamber processes large volumes of water without becoming a bottleneck. Three 4" inlets and outlets make plumbing straightforward and keep water moving smoothly through the system.

• 9,000 GPH max flow for demanding koi ponds
• (3) 4" inlets/outlets for flexible, high-volume plumbing
