MQ 210GPH Submersible Water Pump (800L/H, 8W) with Filters and Water Nozzles, Ultra Quiet for Aquarium, Fish Tank, Pond, Fountain, Hydroponics

Super powerful yet very quiet. You can’t hear it running. Comes with many attachments that easily screw in for bubbles and reducers which I needed. I had to turn this baby all the way down and use the supplied reducer to make the flow proper for my tank. I have two filters now. One has the UV sterilization bulb and is a weak flow for smaller tanks so I needed another filter capable of circulating 50 gallons of water otherwise the filter won’t pick up the waste on the bottom of the tank.Worth the money. Not for small tanks. Performance is amazing. Quality is great.

I’m using this for my 75gal ice pod. Obviously i am adding chemicals to disinfectant but without the pump the water is stagnant and not filtered. Now I can go 2 months in between draining the water. $$$ saver.Also very quiet.

I picked up this little filter pump as an addition to my preexisting filter instead of buying a new hang on back or canister system for more flow and filtration. It was a bit of a gamble but for less than $20, sure why not. I figured it would add the extra water flow I wanted and additional filtration sounded good for my planted 30 gallon.Definitely a great purchase. I was skeptical after initial setup due to how loud the pump was. By the time I got home from work it had quieted down significantly. I wouldn't recommend this system for anything smaller than a 30 gallon. Even with the flow rate turned all the way down, the pump still pushes quite intensely.It's a great addition to tanks of a particular size to supplement your existing filtration system. Also, being rated for over 100 gallons per hour, it's a great way to keep my tank functioning if my hang in back were to fail.

I was very impressed when I first set it up although it does say it's battery operated but since setting up the air flow it's stopped working several times and stops the air flow inside my tank. I lost three fish today at work. Also the second part of the air tube doesn't fit into the tube.

It has all the other features I wanted, but my application only has 12VDC available. Returned without issue and promptly refunded.

Love it! Works beautifully. Very quiet

works great to circulate and filter water in my frog bog

Easy to install, runs quiet. I have had it for three weeks. It’s on my screened in porch in a 50 gallon plastic pond. Today I unplugged it to clean the filter and when I plugged it back it it would not start. I really liked it. It had great water flow. The price is good but not sure if I’ll buy it again.
