    Highly recommend this sponge filter, this type of filter is great for fry as they wont get pulled into the filter.

    Greater than one week

    I ordered this product June 17, 2020. This was a replacement for another filter that I had used for a couple years that worked great!! I put it in a 10 gal tank with a power head attached. With-in 5 weeks the sponge had caved in on itself and was no longer filtering my tank. I took it out, rinsed it, put it back in and it ran great for about 30 minutes, then it did the same thing. I ended up putting together a matten filter, which is working phenomenally!!! So, I will not be ordering this sponge filter again.

    Great for creating more surface breakage.

    There werent really any instructions but it after googling some other sponge filter setups it was easy to do. With my new baby axolotl this creates a wonderful environment that has filtration but very low current. She still goes up and climbs on the filter to play with the bubbles though! I do wish there was room to easily add an air stone since the bubbles coming from mine are pretty big and a little loud. Im sure I can figure it out reading through some more reviews and researching a bit more. Overall a good buy, a nice cheap alternative to an over the back filter that works well in tanks that need low flow for animal comfort!

    The filter works fine and keeps my fishbowl water nice and clear. The only problem I have had with it is that when you put it into your tank it expands to about twice the stated size and therefore takes up a lot of room in my small tank. It works great though so I do recommend it.

    Sponge filters arent complicated. This one is good. It has a very well-weighted base and the foam density is just right for my aquarium. Its large. I dont recommend using it in anything under 50 gallon tank unless you dont mind losing some space for your water critters and plants.

    As expected.

    Bigger than I thought, but it’s a good filter. Sponge filters work great even if theyre unsightly. Update: Great filter! There was almost no flow in my 40g with just this though, so I do have to run a HOB filter. These will work fine for bigger tanks, but I would invest in a powerhead.

    I added this to a 45g tank with a HOB filter already installed. It has added movement to the water and made it very clear. I was really surprised how effective something so simple could be.

    Got it quickly and seems of good quality. Had it hooked up now for three weeks and honestly not that impressed so far but maybe the bb hasnt built up yet. My tank is no more clear than what hob was doing or my perimeters.

Biochemical sponge filter provides both mechanical and biological filtration. Simply install an airline into the unit and provide both aeration and filtration for your fish. In addition, the 4 1/2 inch sponge filter traps waste particles mechanical.
