The EZ Pond EZ300i koi tank provides a professional, high-quality solution for koi quarantine, temporary holding, and treatment systems. It uses heavy-duty fibreglass construction, which delivers excellent strength, durability, and hygiene. As a result, serious koi keepers across the UK trust this tank for reliable fish care.
Because the tank features a smooth GRP finish, it cleans quickly and prevents waste build-up. Therefore, you can maintain stable water conditions with minimal effort.
Infinity Viewing Window for Easy Fish Monitoring
The EZ Pond EZ300i koi tank includes an integrated infinity viewing window that allows clear side-on visibility of your koi. Consequently, you can inspect fish health, monitor behaviour, and observe treatments without stress.
Furthermore, this feature makes the tank ideal for quarantine systems where regular inspection remains essential.
Designed for Efficient Filtration Performance
The tank comes with a factory-installed 4 inch bottom drain and stainless steel fry grill. Therefore, you can connect it directly to gravity-fed filtration systems such as drum filters and biological units.
Because of this professional design, waste removal remains highly efficient while water quality stays stable. As a result, maintenance becomes easier and filtration performance improves.
