SuperfishKoi Flow 30 Set 1,800L/h 25w

We purchased this to aerate our new pond upwards of 20000 litres. Very powerful for such a compact and low energy unit. Has six outlets: we use only three of these so in that case make sure you close off the spare air lines securely.Has been working 24 hours a day for some weeks now and has transformed the pond oxygen levels as the air stones lie on the bottom deepest part of the pond and transfer water up as bubbles to expose to the air.Prevents stratified oxygen differences and really energises the fish.

Nice bit of kit for my pond I have 6 stones coming of, runs very quiet and I have a plastic box over the top to keep it water tight as rain water will still get into them and stop them from working, that’s my only criticism they are not waterproof.

This is a machine that pumps air into a fish pond in order to oxygenate the water. I’ve had a succession of other makes, and thus far the performance puts all of them in the shade. It was pleasing to note that the product came with spare diaphragms: when my previous pumps from a different well-known manufacturer required repair kits to be purchased- at high cost!.AW

I was amazed at how powerful this pump is compared to cheaper pumps. Almost turned my pond into a jacuzzi and the koi love it. I like that it comes with replacement valves as these are the first to lose flexibility with air pumps.

Very quiet brilliant air conditioner desperately needed due to the recent hot 36 degree weather fish were starting to suffer so couldn’t have come at a better time three days on and the fish are very much happier water test showed vast improvement in quality so very pleased would defo recommend to other koi keepers

Very powerful, we only used two of the air hoses, fish love it and it keeps the pond healthy. Really pleased with it

Used this pump to run my tempist filter excellent value for the money easy to set up

Very powerful air line.all 6 lines pump air very fast. Koi love it they play in the powerful stream.
