Half Off Ponds Pond 2.8 Cubic Feet Per Minute Subsurface Aeration Air Pump, Ponds to 8,000 Gallons, Pond Depth To 15 Feet - PA-65

I've been using this pump for 3 years, non-stop in a 10,000 pond with 300 fish and it has worked perfectly the entire time, and it's still going strong.

I use mine in my Fish room and it has worked well is decently quiet, and has good value for your money

The air pump is solid and produces a powerful output. The weighted hose was just as advertised and sank down into the water effortlessly. The 8 inch air stones were great at pushing out voluminous bubbles. The provided hose clamps must have come from another device. When relaxed, they shouild have been smaller than the hose, so that squeezing them would cause them to open up to be fitted around the connection. They were all larger than the hose diameter and useless in setting up the system. If you buy this aerator system, you will need to provide your own hose clamps. The system works well so far, but has only been operating for a few days. It seems very solid and well made, but time will tell.

Great pump.

Works good and is very quiet.

It's too soon to really comment on the durability/reliability of this pump, as I just got it, and only ran it for about an hour to make sure it was working (gotta do my fall clean-out before I turn it on for the winter). It seems like it will be a good one...and it is quiet. When I first hooked everything up, I discovered one of the two aerators was not working properly. I contacted the company through Amazon, and received 2 replacement aerators immediately! So, time will tell on the pump itself, but right now this gets 5 stars for amazing customer service!

This aerator has always been noisy. Having never used one before, I just thoughts that's how they sound. This was stored inside per instructions. Set back up but this year but it generated no air. Took apart to look at the diaphragm and discovered why it was so noisy and not producing air. There are suppose to be 2 hooks that the right and left diaphragm arms attach to which allows the diaphragm to move in an out. There is only 1 hook so the left side just rattles. Internal components are also very rusted. This was kept under a waterproof box during seasonal use. Company does not sell a replacement diaphragm that I can find. Not a good investment if you expect to use in a home pond.

I had a couple months of perfect air output, and then one day it just decided to stop making pressure. The pump still turns on but nearly no air pressure ..
