Aqueon QuietFlow Internal Filter with SmartClean Technology Medium

it's very quiet. It's an under water unit which I like. The filter is biodegradable. It is supposed to last a month. This filter is for a 15 to 30 gallon tank. I have a 20 gallon. It says on the box that the water cycle is 75 to a 150 gallons per hour. Definitely read the description.

Worked as advertised. And runs very quietly underwater.

[This review was collected as part of a promotion.] I installed the aquarium filter by myself it was super easy and nice that it came with a filter cartilage. I find that it's highly efficient and maintenance on the aquarium before much more easier to manage. It very small and slick is it fits right in without being an eyesore and the noise level is moderate.

[This review was collected as part of a promotion.] This Aqueon internal aquarium filter made it easy for me to care for my fishes. It is super quiet and easy to install. On top of that, it has a smart cleaning technology that will keep your fish tank and fishes looking and feeling clean, clear, and most importantly healthy. Unlike the other brands, this filter has an auto pump, which doesn't require any priming. I highly recommend this amazing optimal performance quiet fish tank filter machine.

[This review was collected as part of a promotion.] This Aqueon QuietFlow filter is great! It was really easy to set up and works perfectly in my small tank. The water stays clean, and the SmartClean feature makes water changes super easy. It's quiet and doesn't take up much space. I also like that you can adjust the flow and use it on framed or frameless tanks. Very happy with it!

There is so much carbon on the filters that it turns your hands black and clouds the tank.

[This review was collected as part of a promotion.] This was pretty easy to install…overall fits my 5 gallon fish tank that I have nicely. Gave a deep clean to the fish tank before installing and not sure if the filter needed to adjust or if the new water needed to balance out with the chemicals but the water did get a little green the first few days but cleared right up. Overall, a good experience.

Doesn't do a god job of keeping the water clean. After only 4 days the water is cloudy after doing a fresh water change prior.

The latch is too small to hang from the rim of the tank and the suction cups don't work well-the filter sank.

this was not the product that I received it was not in stock
