This product allows you to transform your standard 4″ x 2″ Bottom Drain to an aerator. This is ideal if you have or are thinking about buying a standard   4″ x 2″ Bottom Drain, you can simply change it into an aerator at a later date.

Why An Aerated Bottom Drain? 

The benefit of having an Aerator on your Bottom Drain is the rising air bubbles makes a uplift, this circulates the water towards the Bottom Drain making the Bottom Drain up to 30% more efficient at removing debris and waste from the pond. Not only does it help with the performance of the bottom drain but also aerates the water making for a healthier environment in your pond

This design of Bottom drain features an aerated dome; the aerated dome has a ring of perforated hose that sits neatly on top. Not only does the aeration benefit your pond and your fish but it also helps with pulling debris into your sump making it more effective.

The aerator on this dome is run the diameter of the Bottom Drain dome and is 830mm in length to be exact. The aerator is fitted with an air input tee that will accept flexible airline with an internal diameter (ID) of 4mm. This kit comes supplied with 10 meters of flexible clear PVC airline (4mmID-6mmOD)

Installing to an Air pump

We recommend the use of an air pump between 20-30 LMP for sufficient performance.
Simply connect the airline that is attached to the Bottom Drain to your air pump. For ease of assembly place the tip of the airline in warm water for a few seconds and push onto the chosen fitting.
