uxcell XINYOU XY-380 Aquarium Fish Tank Biochemical Sponge Filter, 4-1/2-Inch (1-Pack)

Much larger than I was expecting, which in the end is great! Very happy with the product. Surprised how under-rated this type of filtration is for aquariums. Performs soooo much better than HOB filters and is perfect for smaller tanks where you dont need a canister filter. Sure it takes a larger portion of the tank up but my fish and shrimp do much better with a number of available microorganisms that these foam filters make a great home for.

I love this sponge filter, simple and easy to use, the bottom is weighted enough for it to sink immediately after squeezing in water, great place to grow beneficial bacteria, bought another I liked the first one so much

it is great for a 40 gal, or max a 50, depending on stock, I use this on a breeder 40 with a pair of gold severums, seems to be peaceful enough and keeps water clean, Mesh seems tight and not very porous but works

Great filter

Great for breeding tanks

If you want to have a nice clear tank, this water buffer is perfect. Just attach airline and hook up to your pump.

5/5

Good quality product. It works.

The is a really good sponge filter at an every better price than anywhere else. I use it for my breeder aquariums when raising newly hatched baby fish fry, as other filters will kill the new baby fish. Works well and the sponge contains your bio.

The filter is not that heavy as it keeps on floating in my 30 gallon aquarium. Water looks clean with the filter.
