Water Change Hose – 15mm Diameter

This 15mm bore water change hose provides significantly higher flow volume than standard airline-based siphons, making it the practical choice for draining and filling large aquariums quickly during water changes. The wide bore allows gravity to drive a fast, steady flow without the pressure restrictions that narrow-bore hoses impose.

The 2m length gives enough reach to drain into a floor-level bucket or barrel, or to route the hose to a drain in a fishroom. The flexible PVC construction resists kinking during use and coils compactly for storage. The smooth interior prevents algae adhesion that is common in ribbed hoses.

Pair with a thumb-stop clip or in-line valve to pause flow quickly without lifting the hose from the tank.
