Norlog 260 Gallon Giant Koi Pool

This Norlog 260 Gallon Giant Koi Pool is made up of a 175 gallon pool with an overwintering sump, that adds a further 85 gallons below ground to a maximum depth of just over 1.2m. This makes it ideal for Koi carp as their immune system shuts down below ten degrees, which is why Koi carp seek depths of over a metre to adjust their core temperatures - in winter and summer. On some occasions, these pools have been used for emergency holding tanks or for quarantine due to the ease and speed of build. The liner is manufactured from strong EPDM rubber. In order to provide the sump an excavated hole will be required underneath the pond.

Helpful notes on installation:
