FEDOUR4W 5W Aquarium Air Pump, Dual Outlets Oxygen Pump, Ultra Quiet Aquarium Bubbler for up to 200 Gallon Fish and Turtle Tank (5W for up to 200gallon)

UPDATE: So company apologized for faulty one, sent me a new one and HOLY COW this does work amazing so much quieter than the first one! If I didn't see the bubbles I wouldn't know it is on! So I have to say now that I must have gotten a dud the first time because it was never this smooth or quite. Also customer service is wonderful. Company that stands behind there stuff! Can't beat that! So I would have to say now that I would recommend this even if you get a faulty one they will set it right. Now running three filters (Two 20gal and a 10gal) and an air stone, may even be able to add two more air stones like I want with this flow. So this worked pretty good, not really quite unless on the med to low setting, to power a few (two 10 gal and one 20 gal) sponge filters for two months. Although about a week ago in the middle of the night we were awoken by an extremely loud buzz (almost mini chainsaw loud) now I have to combine all four lines just to run one filter.

Before I had a name brand pump and after just a few months one side gave out so I replaced it with this one. I thought the old one was pretty quiet until I got this pump and it is silent and more powerful than the name brand pump. Absolutely recommend!

Overall this is a great product and I may use it on something different in the future. The directions were clear, set up was easy and the noise wasn’t bad (it is sitting on a padded surface so that probably dampened the noise). There were some kinks in the tubing that eventually worked themselves out. The only problem was the GPH wasn’t powerful enough for my hydroponic use. That is my miscalculation. I had hoped to aerate four DWC buckets with the one pump. I tried larger air stones but still didn’t generate sufficient bubbles to adequately aerate the water. I did try a more powerful pump that seems to adequately aerate four buckets and I will be purchasing more. I am using this pump temporarily but use all four lines in one bucket.

The unit does perform very well and so far, I have not had any water back-feeds to check out the values because of the loop in the hose I have at the top of the tank.The unit is louder than I would have liked, but I can turn down the regulator for the air on the unit to quiet things down. However, I like water movement within the tank so that my fish stay more active moving around and there is no doubt that there is plenty of oxygen in the water.

Replaced a pump that was failing. This one is much quieter than the old one and delivers a lot more volume. I like the fact that you can adjust the volume too

It’s a nice unit, feels like high quality, extras are high quality(hoses, check valve). The noise at half is ok, noise at full is unbearable loud. Full throttle is very weak for an air pump. I have 4 stones running and the bubbles barely come out. I’ve swapped hoses, check valves, removed restrictor…it’s a very weak pump. I have some $5 pumps that are more powerful. Of course the $5 pumps are junk and loud and not as high quality.

I liked that it puts out a lot of bubbles, has an adjustable dial, and has 4 outlets but it’s gotten progressively louder as time has gone by and gets very hot now after 8 months of use. It also seems to vibrate VERY hard. If it wasn’t getting so hot already we could put it on some kind of cushion but I worry this will compound the overheating motor issue and further reduce its longevity.I hoped to reach out to the seller to trouble shoot but haven’t found where to do so. Likely will not repurchase since we didn’t get a full year of use before it began having significant problems.

Nice color, solid footing with soft cushioning for the floor, the tubing was also soft and flexible for ease of use. It also coms with very nice Bernoulli adaptors, presumably to provide a top drip water supply from the aeration tank, the flow of which can be adjusted with a handy nob on the unit's top, or by simply adjusting the diameter of a convenient needle valve built into the adaptor.
