Aqueon Quietflow Canister Filter 300 GPH - High Efficiency Aquarium Filter for Freshwater & Saltwater Tanks - Ideal for Large Fish Tanks, Reef Aquariums, and Aquatic Plant Setups

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!!
