Aeration in a fish pond is an essential part of the eco system. By providing adequate air, the water remains rich in oxygen that benefits the fish and gives them the healthiest environment to live in.
The Kockney Koi Sinking Airline has been designed to sit along the natural contour of the pond side, eliminating the need for weights to keep it in place. Unlike standard airline, the tubing is make of thicker and heavier material, making it easier to sink and sit in place. It is also resistant to UV light exposure and is tough external material makes it resistant to kinks and damage
The airline also blends in with the colour of the pond liner and lays discreetly in the water and along the base of the pond when connected to a robust airstone.
The tubing comes in 2 internal diameter sizes - 4mm and 8mm and is offered in a range of sizes
Please note - 5m, 10m, 30m and 100m are precut rolls. Each item ordered will be sent in seperate precut packs
eg if you order 2 x 30m and you will recieve 2 rolls of precut 30m and not a full 60m length
The 1m and 15m are cut from a roll per order. So if you need a set length that is not available as a precut, then add the required length into the Quantity box
eg for 7m order a Qunatity of 7
