A Bakki Shower is a high-performance biological filter system used in koi ponds—especially popular among serious hobbyists and in Japanese koi pond setups. It’s known for delivering exceptional water quality and oxygenation, promoting strong fish health and clear water. 

1. Water Pumped Up: Pond water is pumped up to the top tray of the Bakki Shower.

2. Spray or Flow Bar: Water is evenly distributed across the media via a spray bar or flow distributor.

3. Media Trickle: Water trickles down through multiple trays filled with high-surface-area media (like Bacteria House ceramic).

4. Biological Action: Beneficial bacteria living in the media break down ammonia and nitrites into less harmful nitrates.

5. Return to Pond: Oxygen-rich, biologically filtered water falls back into the pond, often creating a waterfall effect that adds even more oxygen.
