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

This a big sponge filter,much bigger than I expected.I hooked it up to help me cycle a tank but now its in storage until I need it again.Thanks!

My tanks have several filters - you cannot over filter. This is just another type.

My least favorite sponge filter out of the 5-6 I have. I dont feel like this really traps anything or helps to filter my tank. I use it more as a bubbler for my gold fish. They seem to like to swim around, behind, and over this.

Heres where everyone else went wrong: 1) It collapsed when I put a powerhead on it. - Well of course it would, it isnt a coarse foam, its a very fine pore cell foam, and is made to work with an air line, not a power head. 2) It doesnt create any suction. - Wrong! I held it up with the tube just above the surface of the water, and water was pouring over the top of the tube, so... unless its a magic filter that created water from nothing, the water coming out MUST have been the water flowing through the foam. 3) It floats and I need to put a rock on it to hold it down. - Yeah, ahh, try squeezing the air out of it first, since you know, its a SPONGE. Squeezed mine til the bubbles stopped, and it sank like a lead weight. 4) A disaster. Will never filter properly with a reg air pump & design flaw causes back pressure that can burnout pump. - LOL, okay... Ive got mine on the cheapest possible Whisper pump, and it works fine. Not sure where your air flow engineering degree came from. 5) Only lasted less than 2 months. What a waste of money. - Considering that it probably takes that long to get a sponge filter seeded with bacteria and matured, yeah... 6) Killed my fish. - No, what killed your fish was that you relied on a brand new filter that had zero live bacteria living on it yet, and you didnt cycle your aquarium. It has to cycle. Learn about cycling. Google, Cycled aquarium before bashing a five dollar sponge filter. As to the bad reviews about missing parts, I cant speak on those... mine had a every part included. And, I have been using Jemco sponge filters for 20 years, so I was skeptical about these. I went with it because I use black sand and have a black background, and Jemcos are light gray. Only reason I switched. I will say they ARE loud since they have no airstone. My solution was to use a different air pump, which eliminated the resonant hum created by the strong one I had on there first. There is a video on youtube about modifying these to work with an airstone if you dont like the design. I may do this in the future, but I doubt it. Id rather sit back and enjoy watching my fish.

i am very happy with this product i have never used this type of filter before

Did and works as advertised

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.

The weights that hold down the filter is a little light, cheap.

Lo compraré otra vez en el futuro

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