BlagdonPond Oxygenator 1800, 6 Outlet Air Pump for Ponds Up to 10,000 Litres (Koi Ponds Up to 5,000 Litres), Suitable for Aeration and Oxygenation in Hydroponic and Aquaponic Systems, Green

The media could not be loaded. A great bit of kit! Does as it says!SO much quieter than the one it replaces and much better is waterproof so can be left uncovered. Feels heavy and well built.Almost silent in operation!Paired it with black singing air pipe as there’s nothing worse than floating white ones!We have happy Koi again! 🐟A great buy!

Excellent pump and very quiet

It does not come with air pipe

Great product, I have used a lower power version for many years and decided to upgrade to a more powerful version.

Quick deliveryPump as it says on the box

Very powerful

Powerful air pump, heavier than anticipated, but sits firmly at side of pond. Produces plenty of bubbles to pond .deducted a star as no plug, pipes or air stones

My pond is 5,000 litres so I purchased the basic 1800 model, which is rated for 10,000 lites ( or 5,000 if you have Koi, which I don't), so it was massively overrated for what I needed. That said, it was just about the only one I could find that was totally weatherproof. I declined the option to buy air stones and tubing with the order and instead went to my local aquarian to get advice. In the end I opted for 50mm air stone balls, some decent tubing that won't go brittle in winter and some inexpensive one-way valves on each airline as a precaution against a power failure, which can occasionally a pressure differential to syphon water up into the pump. I only use 4 of the 6 outlet points and the surface of my pond now has a healthy amount of movement. Within days the water was so much clearer, the fish became much more active and my pond plants thrived, particularly the lily pads and the water mint.Despite it having rubber feet, the pump can resonate on the wrong surface. I placed mine on a small slab on top of a shallow mound of loose sand/earth mix, which seems to absorb everything and I can barely hear a thing. Really happy with this pump, my pond looks so much healthier and I would recommend it to anyone.
