A bit expensive but fits
A bit expensive. I actually took the cartridge apart after a month and replaced the media with two pieces of cut-to fit carbon infused filter pad (imaginarium brand at Petco $6 for a package large enough to cut about 20 filters out of) but after 3 times disassembling, the tabs broke off. Definitely going to continue doing that with these new ones.

Great for small tanks
I have a 5 gallon tank, and this filter is perfect. It flows slowly, so it doesn't produce an overly powerful current in the tank. Easy to replace. Thank you for making the replacement filters available on Amazon.

I've used these for years, in a 5 gallon tank, set on lowest setting and plants in front of the single spout of the pump part that this attaches to, with much success.
