Aquarline Hailea Aco-9820 High Output Pond/Aquarium Air Pump, 3600 Liter/Hour

Had for 6 months and all good .Its powering 4 sponges and a splitter allows me to run my brine shrrimp feeder.I bought this because it has metal outlets ,other pumps ive owned the plastic outlets always deteriate and the plastic tube get stuck and brake off. Volume is not bad , its not loud but a hum can be heard .Its about the size of a small loaf of bread.I have it on half power .

I already had one of these pumps which has been on for the last 2 years without any issue so purchased a second for a second pond. Its pumping into an outside pond and I have it installed in a waterproof electrical box, with the tubes feeding out where the electrical cables would normally feed.Gives good bubbles for the ponds and it isn't noisy (noise tends to happen if the box is sitting on something that amplifies the vibrations). Happy to recommend.

The reason for four stars rather than five is because it says on the box that the pump is super silent, it isn't .It also isn't terrible, it is a noise level which you could learn to ignore. I have this pump in my kitchen where it is running three airstones for three tanks and I can easily forget about the noise. I could ignore it in my living room too but I would say it is a definite no no for my bedroom tanks.Having said that the pump does work very well. It gives lots of bubbles which is just what I needed to add lots of air for my fancy goldfish as our house gets very hot and the oxygen was getting low in the tanks. since having this the fish are much happier.All in all I am very pleased with this pump.Works well, good price, what more is there.

Very solid bit of kit. Robust and works very well. Pretty quiet with a great output. I have 6 air stones running of this, had to get valves to reduce the flow as such good flow rate. Well worth the cost and hope this lasts. You will be pleased with this.

This is my second ACO-9810, my first has been in use 24/7 for the past 4 years & is still going strong, much better than any other pump, I've had 4 x Eheim 400 & a Fluval Q2 all of which lasted between 1-2 years before either failing or needing the diaphragms replacing, this hasn't needed a thing. Yes it's huge but it's quiet & it pumps out 10x that of any other aquarium pump.

I have just set this up in my 250 litre aquarium.First impressions are very good.Loads of air through the 2 under gravel filters and 2 very big air stones.The only extra noise I can hear is the extra air. But the pump is no louder than the two ordinary pumps I took out.The aquarium is in my lounge and there is no need to turn the TV up.I have just checked the noise level, 35db. I am 5 feet away from the tank.Very impressive.

Didn't work out of the box, I think it is a faulty unit, due to low stock I then replaced it with a 9810 and I'm very happy, really quiet and powerful

Great power for hydroponic use.
