EZ4000i – infinity (Twin Storm Drains)

The EZ-Pond EZ-4000i Koi Tank is a professional-grade fibreglass holding system designed for serious koi keepers. Importantly, West Midlands Koi are the only authorised UK stockist. Therefore, you receive genuine manufacturer supply, full warranty protection, and expert technical support.

Because this tank is engineered using high-grade GRP construction, it delivers outstanding strength and durability. As a result, it maintains structural integrity even under full operating load. In addition, the smooth gel-coat interior improves hygiene and makes cleaning straightforward.

Furthermore, the built-in infinity viewing window provides a panoramic display of your koi. Consequently, you can monitor fish health clearly and confidently.


Designed for Serious Koi Systems

Unlike standard plastic vats, the EZ-4000i offers commercial-level construction. Therefore, it performs reliably in both hobbyist and dealer environments.

Moreover, the reinforced fibreglass shell resists warping and UV degradation. As a result, the tank remains stable over long-term use. In addition, the internal finish reduces debris adhesion, which supports better biosecurity management.

Because quarantine and grow-on systems demand consistency, this tank delivers dependable performance in controlled environments.
