These filters were just what my new tank needed. Transaction was smooth and I would gladly do business with this seller again!

Fit perfectly in my little hexagonal 3-gallon tank.

You can buy 12 of these filters for $15 on the Petsmart website.

I really like these, they help keep the water clean.

Worked well

The water looked dirty after use. For the second time we had to soak the filter and rinse 3x until the black junk is clear then it worked better.

Fit perfectly Good long lasting filter

Exactly what I expected and needed for our tank

Found it to be essential for a clean and healthy tank.

My 3.5G tank calls for these for the filter and they work great. I get about 1.5-2 months out of two filters at a time and in between replacements I rinse the filters to keep them fresher longer.
