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

Its okay but the weight isnt heavy enough for it to stay down. Really disappointed in that. You think they would know to give a weight heavy enough for the sponge filter. It came with no instructions to really tell you what to do. I mean its simple to figure out and all but theres no way to add an air stone to the filter with out have to modify it. I guess you get what you pay for. I should have bought a better one.

Had I known I would have gotten it late, I would have purchased this item on ebay. Its a great product, delivered late by Amazon. As always, I continue to be disappointed.

Great water processing power! The is on beast mode. Love this thing

Works great and cheap too, only 6$

One of the best sponge filter I have ever had. Two of these run my 100 gal with no difficulties at all. Tip: try and clean your sponge filter once a week when you do your water changes. Dont wash them under the tap water...instead, use a bowl and halfway fill up from you tank water and then squeeze your sponge in that water a few times and then dump the water. This way your filter doesnt loose its bacteria load which is beneficial for the tanks chemistry.

Works like it should

very good product great seller

Great additional cleaning of small debris.

Nice maintenance piece

I use this in a Salt Water QT tank and I feel much better knowing I have that extra bit of oxygen in there to counter balance the various medicines I need to treat the fish with that often strip the water of oxygen
