Tetra filters are the only ones I have ever used. I was thrilled to find a 12 pack box of them. I have a large aquarium and need to change filters often and this saves having to keep ordering them so often. Thank you, Chewy once again for your great products and service.
trying something different.

I usually get 6 weeks out of these filter. I don't throw them away... I rinse and add new charcoal to keep the cycle going.
Be sure to rinse them in the tank water that you removed. Drain at least 50% of the water. Then replace it with fresh water.
