Shop the range

Choose a size and inlet, then add it to your basket. Each size shows its recommended air flow in litres per minute, so you can match it to your air pump. Need a length or layout that isn’t listed? Ask for a custom build.

Flow rates are a recommended range, tested at 1.2m water depth with 8mm ID air hose (4mm for the mini range) 5m from the pump. Your results will vary with your pump, water depth, hose size and hose length. If you’re unsure what size to choose, get in touch with your pond volume, depth and air pump model.

Custom builds

Much of what we make is built to order. Air bars can be made to any length up to 6m, curves and rings to bespoke sizes, and manifolds with mixed outlets in whatever layout your filter house needs.

Why micro-bubbles

Our membrane has thousands of pores between 0.5mm and 1mm, producing bubbles far finer than a conventional air stone or dome.

More oxygen reaches the water
Small bubbles rise slowly, so they spend longer in contact with the water before reaching the surface. Large bubbles race up and release most of their oxygen into the air.
Better circulation, calmer surface
A long curtain or column of bubbles lifts and moves water across the whole pond, without the surface boil that hides your fish.
Built to last in a pond
Virgin rubber membrane with an antimicrobial finish that resists algae, 316 marine-grade stainless weighting inside, and UV-stable POM and PVC fittings. Clean with a garden hose or soft brush.
Soft on fish and liners
A smooth, soft exterior with no exposed frames or sharp edges. Safe with salt and common pond treatments used as directed.
