AquaMiracleAquarium Air Pump Commercial Air Pump with Aluminum Housing, 600/1000/1200/1750GPH Fish Tank Bubbler Pond Aerator for Aquariums, Ponds, Hydroponics

Works great, quite, well made and light weight

Well she’s a hummer alright, but it’s not as annoying as I expected, especially when weighed against what a tiny little powerhouse it is! I have the 1000gph and it’s HALF the size of the big Tetra Whisper with easily 5X the power. (One pump to rule them all! ✊😜) I will be putting a hose and a breather filter on the intake, as one review claims it helps with sound-dampening. I’ll also put it in a box covered with closed-cell foam padding. I can run one of the air lines into the box, making it self-cooled. Honestly though, I’m in no hurry. It’s really not all that loud. (It’s in a tank stand/cabinet with closed doors, which helps.)READ THE INSTRUCTIONS. It has an intake filter you must clean regularly. I bet some bad reviews are from people who didn’t bother to read that. (Adding a breather filter should mean less cleaning maintenance 🤞)

First, understand I did not buy this to aerate an aquarium but I am bubbling air through water. OK. I'm using this pump to pass air through a Birkeland - Eyde reactor. So the air flow goes from the pump into a 2 gallon glass jar, then through a second hose out to a 1 liter jar to bubble through water. I bought the 18 watt model. Oddly, it pushes more air than needed through an open tube and I actually had to restrict the air flow down by 50%. But once I attach a ceramic air diffuser, it completely stops working. It will push air down to the diffuser, where it just stops. I have no explanation for this but I am using it a little differently than it is designed for.It's very well made, reasonably quiet - remember it is commercial grade like for use in a restaurant or something which is why I bought it. For that function - aerating a lobster tank, large fish tank, something like that, this is a very good pump. Very small and easily concealable. Despite its inability to push air through a diffuser in my specific application I give this pump 5 stars and would buy it again.

While I was very impressed with the air flow of this pump, and the noise was greater than expected. Since it is placed in a protected location outdoors, it is not causing noise issues inside our home.I discovered that the much greater noise and lack of airflow in the past month was due to racoons having chewed into 3 of the 6 air stone lines in our pond, plus one of the air stones had been pull off its tubing. I only had two air stones operating, but had a major loss of air pressure right at the pump and in the pond. After tension wrapping the chew holes (I will replace the tubing soon) and cutting the damaged main tubing at the pump end, pressure resumed to normal.The noise level of the pump is higher than when it was first installed, but it is outdoors, so it is not that much of an issue. Our previous air pump now costs 4-5 times as much, is very quiet, but the air flow is about 1/10, so it is not of much value to us. We are sticking with this manufacturer, especially since they responded within one day to my concerns about the airflow issue, BEFORE I discovered that the problem was not the pump, but racoons thinking plastic tubing is food.Very good response time and excellent customer support by the company. Emails are only available via the address printed in material which comes with the order.

I'm using this for my DWC system and using 4 valves currently. Works great and my plants are thriving. It does get a little hot and vibrates a decent amount, but I took a suggestion from another review and hung it up. I would recommend.

Why did you pick this product vs others?:Quite and amount of air flowNoise level:Relatively quiet

Using for a laser cutter, this bad boy outputs a perfect amount of air to provide a nice assist. I ended up using some food-grade silicon tubing as airline and I couldn't be happier. It does make some noise, so don't go after this if you are looking for something quiet.

Good output but may get more airflow in the future. I brew compost tea every week and use a bubble snake. Not quite the aeration I would like but a very sold product.
