AllPondSolutions Outdoor Koi Fish Pond Air Pump Kit Air Stones Included, Air Hose, Return Valve

Great pump perfect for my needs, upto 6 outlets Great airflow, large airstones, good price and quality, put mine in a ip66 enclosure to further waterproof everything, very happy with my purchase.

Great unit

Lots of water flow through them all. Relatively simple to put together. Pump seems good quality. Make sure you put the one way valves the right way. Suggest testing own first as its a little fiddly to put together. Seems to have helped the water lots!

The media could not be loaded. Very impressed with the air output from this pump and the shape of the air stones work really well.I ordered this to replace a pump that was in an electrical box (it wasn't waterproof) and the design of this is clearly all weather so no need for the box. I looked at a lot of options and this is a brand I use for water pumps and filters (all proving reliable for 12+ months) and the output vs cost is very good comparing with other brands.On this pond I am only using 4 of the outputs (the remaining two are linked together) and the output for 4 airstones is brilliant. I didn't use the clear tubing as I use black irrigation tubing for the aesthetics, but it's always useful to have spare.It's early days - been running for 3 weeks, either 24 or 12 hours/day and no issues so far.There is no noticeable sound from the pump, at least nothing that is discernable above background noise.So impressed I purchased a second one for another pond! I would highly recommend and the increased air and water flow around the pond has improved water quality within a week even despite the really sunny weather that we are having right now. (The bag of water cress from the supermarket might have helped with that too!).

Its been bubbling away for a month with no issues.Very quiet

The media could not be loaded. So far so good.Lots of bubbles.Easy to set up - one way valve has an arrow indicating the direction of air (fit them so the arrow is pointing away from the air pump).Power cable length 2.8 metres on the '13ltr a minute' version.

Extremely efficient pump which has added the fish during the recent heatwave

The product looked neat and compact easy to assemble except that the plastic piping which is attached to the air balls and air outlet was too small to slide on. I know it has to be a very tight fit but the piping was just too small. Had to send item back.
