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

its a good filter,but way too big!

Quality product

Ok

As described. Can’t use air stone.

I think these would be GREAT for shrimp only tanks (in fact thats what Im gonna do with mine) but for fish tanks I dont think they perform well. These are so fine that they clog extremely fast and just basically becomes an airstone/bubbler as no water will be moving through the sponge also the lift tube is very short, the lift tube should be at least twice as long. If anybody knows where to find compatible tubing please let me know! Ive checked so many places, Ace, local hardware places, Walmart, Jo-Ann etc and cannot find any tubing for it. This is important, wash these out extremely well before you put it in your tank. When I opened my two up, they absolutely reeked and stunk up my kitchen. Wash out thoroughly with warm water as some oily residue also came off of mine.

Works great

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

I like using sponge filters as secondary filter to Aquaclear HOB in larger tanks.

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

This is great! No more foggy water. I am so happy with this.
