    It’s a pretty good pump, has a very minor downfall but the operation of the pump itself is flawless….

    The only downside I am experiencing is the lid of the pump is often rattling and be annoying would be easily fixed with some type of sealer for the lid to keep it from being plastic on plastic and help seal the lid on more secure

    If not for that 1 minor flaw ide give it 5 stars it’s easy to take apart and clean every single component ๐Ÿ˜Œ and the pump itself really is quiet as you see it’s in my room so I need to be able to sleep this pump is perfect ๐Ÿ‘Œ I can make it almost like a really soft running creek noise and pass out almost instantly ๐Ÿ˜ด๐Ÿ˜ด๐Ÿ˜ด๐Ÿ˜ด

    Im so glad I decided to buy this. At walmart a 10 gallon filter was 40$ and i found it here for such a better price. It works really well, its not too loud and looks pretty decent.

    This product is actually genius. Enough so, that I am actually writing a review. I thought that filter companies have given up on trying to improve the engineering process of their filters. I have been seeing complaints over the motor design, but that’s understandable unless you have a background in engineering or have experienced the filter in action.

    Basically, by disconnecting the motor from the base frame of the filter, the vibrations caused by the motor are now isolated and suspended in the water, which absorbs the sound, and prevents the actual shaking of the filter compartment that a lot of people have issues with when it comes to noise (even has additional shock absorbing material to further prevent transfer of vibration). This filter is S I L E N T. I do not hear it unless I lift my aquarium hood and put my ear to the water. I’ve used aqua clears, marinas, aqua techs, and the older tetra filters, and nothing beats the silence these provide. I have a 20 gallon aquarium 3 feet away from where I sleep and I hear nothing, I was super concerned I would have to relocate the tank after setting it up, but this filter is king.

    Also, the filter output chute is genius for providing agitation of the water surface (which you need, otherwise your fish can’t breath because that’s how oxygen is introduced into water, through gas exchange). You can see it actually reagitates the water even before entering with the slight “dent” in it. Even the bimedia plastic flask impressed me, the curved “resistors” on top of it gives a really nice place for bacterial to cluster and and dilute the water for more aeriation.

    It also comes with a new kind of filter media (which I’m sure is great, but seems to be expensive and I used my own media configuration).

    I customized the 20 gallon filter to use aqua clear mechanical sponges, I also cut the included tetra filter media in half, removed the carbon to use as filter floss, and on top I have aqua clear biological media. (3 pack of sponge is $1.82, I use two (these can be permanently reused, clean them when they get nasty with water, there is cheap filter floss on amazon, and the bio media cost me around $3.00 and that is permanent, get size 30 gallons and above for the media since the compartment is big). This is much more sustainable than using the tetra replacement media, but it IS MORE MESSY TO CLEAN. I also use the included blue biological filter compartment as well because it’s just so great. I also recommend an intake sponge to cover it in case you have snails or a betta like me (look at marina filters for an example).

    I have a betta and I lower the flow at night and raise it during the day when he’s out exercising and the kuhli loaches come out to play.

    This is the filter you need.
