D-D Dosing Pump Coloured PVC Tube (4 × 2 m) is a practical and visually clear tubing solution for peristaltic dosing pumps. Supplied as four brightly coloured 2-metre lengths (red, green, blue, and yellow), this set allows instant identification of individual dosing channels, reducing the risk of cross-dosing and improving long-term system organisation.

The high-quality PVC construction provides excellent flexibility and resistance to kinking, ensuring smooth and accurate delivery of additives such as alkalinity, calcium, magnesium, trace elements, nitrate/phosphate reducers, and bacterial supplements. The bright colours also make sump areas easier to navigate, particularly in complex systems with multiple dosing lines.

The tubing is compatible with most popular aquarium dosing pumps, including those found in the RareFish dosing pump range , and can be cut to length for a clean, professional installation. Whether upgrading an existing system or building a new dosing layout from scratch, this colour-coded set adds clarity, reliability, and organisation to any reef or freshwater dosing setup.
