Love this pump. I've attached this to go into a 1" PVC and I run several air lines from the pipe that power sponge filters, uplift powered egg catchers, etc. Pump has more than enought power to supply air for my 4 tanks and BBS hatchery. Stays very quiet and does not get warm. Excellent purchase and I would highly recommend this.

Very quiet and good quality

This air pump runs quieter than any of this type I've ever heard before. It has excellent filtration for incoming air, recommends replacing the diaphragms when they wear out from use, and has the replacement parts readily available. It's got bubbles roiling out of four big air stones and could easily handle more.We've used a series of extremely loud air pumps for our Koi pond for the past decade or so, so loud they've been the first thing we hear when we step out back. They've been pretty much 'disposable', since I've been unable to find replacement parts for them, so they've been tossed out after a couple years.I got a couple of the repair kits and expect to be using this pump for a long time.

The media could not be loaded. Look at photo, about 17db when turned on. Too loud to run in open indoor. Might work if use outdoor and run the line inside.Very sturdy build. Wish it's not as louded. I tried open all line or closed all lines, the noise level stays the same. Doesn't come with adjustable valve and instructions manual didn't mention the need to install blow off valve to prevent back pressure build up.

So far the pump is performing without any issues. I have a few of this pump to run 12000 gallon fish tanks. The pumps runs 24/7 and supply air to 4 diffusers.

The pump was purchased a little over a month or so but I installed it three weeks ago, and it stopped working completely. It was powerful enough to supply air to all the tanks. Ivan install the bleeder valve for some of the excess air but all of a sudden it stopped working completely. I shouldn’t be having problems this early.. I do not recommend this product I have tried to contact aqua miracle and I had no luck so I am returning it back to Amazon

The item has worked well.

I've bought 2 of these neither one lasted a year. Both tore the diaphram. The company sent me replacement diaphrams. I replaced them and they work correctly they were dry and surface rust. I greased them. I suspect that was the problem. There was no oil on the metal parts. They made it right
