KENJI KOI Air Stone Bar

KENJI KOI Aeration Bars – Effective Pond Aeration for Koi and Garden Ponds

Adequate oxygen supply is not an option – it is a prerequisite for healthy koi and stable pond water. Especially in the warm summer months, with high fish stocking density, or after feeding, oxygen levels can quickly drop to critical values. KENJI KOI aeration bars ensure that this doesn't happen.

Aeration Bars as an Alternative to Air Discs and Air Stones

Compared to air discs or air stones, aeration bars produce a uniform, fine bubble pattern over a larger area – for more efficient oxygen introduction into the water. Their slim shape allows for flexible positioning on the pond bottom, even in narrower areas or along pond edges.

3 Models for Every Pond and Pump Capacity

Depending on the oxygen requirement and the connected air pump, three different models are available – tailored to different pond sizes and pump capacities. KENJI KOI aeration bars are designed for continuous operation. No clogging after a few weeks, no brittle ends after one season.

Suitable for: Koi ponds, garden ponds, ponds with high fish stocking density, summer aeration, emergency oxygen supply
