> 3 dayI use this filter sponge on a 55 gallon tank with fish in it. It works great for added oxygen to the tank at the same time helping to filter the tank. I have it in the corner of the tank and its perfect. It has a weighted bottom to keep it from floating. I pull it off every month and rinse off the sponge and put it back in the tank. I would highly recommend this to anyone with multiple fish tanks.

> 3 dayIve had this running in an 30 gallon tank with a single crayfish and it worked just fine. An extremely cost effective alternative for under stocked tanks.

> 3 dayI bought 2 of these, and they do nothing for filtration. I purchased a tiny one meant for 1-2 gallon tanks, that does 10× more filtration than both of these combined. These are basically just huge bubbler attachments. Ive seen many sponge filters, and these are not what sponge filters are supposed to do, nothing attaches to them. Ive never had to clean them, because nothing ever goes to them, and I mean nothing.

> 3 dayWorks great. Got this filter for 29 gallon fresh water quarantine tank. Seeded it with healthy bacteria from my display tank for a few months before buying more fish to quarantine. Delivered on time.

Greater than one weekGreat sponge filters for the price, a bit large but do work well.
