Aqueon Replacement Filter Cartridges Medium - 6 pack

These work. How long the charcoal inside is actually filtering anything is questionable??? I didnt change my filter for a year and a half and my fish are fine.

I got them at a good price but not as much carbon filling as in the same ones I got from petsmart. I had to change these every 2 weeks and the ones from petsmart last about a month!

These are the best filers.

I used the filters with a Aqueon 5 gallon tank.

A+

Liked this filter.

Great deal.

SO so much less expensive here than in stores. Ill order more for sure!!

Good saler

Works great, my 10 gallon tank stays very clean, even tough I dont change these filters quite as often as they recommend.
