Aqueon Quietflow Canister Filter, 300 GPH.

I LIKE the quiet motor, efficiency, light weight, easy clean, overall simplicity in putting this canister together and getting it started! I have a 55 gallon fresh tank and I chose to get the Aqueon 300 (for 75-100 gallons). I always choose overkill in filtration for my tank (LOTS of fish!). I tried using the spout for output (bout 2wks) length wise direction. Liked that the water was circulating-back towards the intake. The flow looked too strong for my fish. Put the spray bar on and it works much better-fish happier! My DISLIKE is the curved part that hangs on the rim of the tank. Doesn't seem to fit right on the rim of my 55 gal acrylic tank. I have to work that out to make me feel more secure about its placement. But I am happy I put the bar on! And I'm even HAPPIER that I purchased my AQUEON 300 canister!!

I had difficulty setting it up the first time. But I wanted to share, especially with Vanessa, when cleaning, before you unplug the unit, turn off both valves at the same time. Then unplug and disconnect the unit and clean it. Fill it back up to the top with water. Connect the hoses, plug it back in. And then turn both valves on at the same time. Starts up flawlessly. Priming it the first time was difficult. But after that easy. Make sure to remember which hose goes where, that will cause you to have to re-prime the filter pump.This is definitely a great product, it’s worth the effort to setup and clean. You won’t clean it as often as other filters. It can easily go a month or two with no smell. (Slider turtle) Color will change is the indicator for me. But never had a smell once the bacteria levels balance out. Took approximately 2 weeks for it to obtain that earthy smell.

Pump doesn't fit under cabinet shelving. Quiet running however. 75 gallon tank with LOTS of cleaning needs meant 3 passes with extra filter before results were seen.

Perfect filter for my 75 gallon cichlid tank. The additional biological balls/beads etc will help greatly!

Aqueon Quietflow Filter 300 was definitely a good choice. I used a Magnum 350 filter for around 15 years. Not familiar with the new aquarium filters, I searched YouTube for reviews and installations. I felt the Aqueon Quietflow 300 was in my price point and appeared easy to setup. I used the installation instructions and the suggestions from YouTube videos for the initial setup. The first few steps went very well. I plugged it in but the water didn't flow through the lines. Others had mentioned the issues with priming the motor. I tried opening the relief valve several times. Each time a little water came out of the top of the canister. So I thought it was ready. I plugged it in still no water flow. I noticed the 'out' water line did not have a lot of water in it. I had someone else hold the out line up so the line filled with water, plugged it back in and it started working. After just several hours, my tank is much clearer and cleaner. I would definitely recommend this aquarium filter.

Garbage. doesn't work right. doesn't have enough pump power to pump for more than a day and/or it just stops working though it keeps grunting. it is garbage. I am using the 75 gal filter on a 50 gal tank. and a 50 gal filter same product on a 40 gal tank. they both suck.

noise level is normal, BUT defintely not loud, I have mine under the cabinet and cant really hear it only if i concentrate to look for the sound, Sheerness is great and its thick enough to put any media you want, so far im happy with it.

Runs like a champ but I'm not sure how to adjust the flow. Will adjusting it with the inlet and outlet valves jeopardize the unit?
