Keep your aquarium water clean, clear and healthy with Tetra Large Aquarium Carbon Filter. Fish waste, uneaten food and other organic matter can cause toxic levels of ammonia and other pollutants which can be harmful to your fish. Tetra Large Aquarium Carbon Filter is made of layers of multi-density floss that effectively trap even the smallest particles and its activated carbon rapidly eliminates odor, discoloration, impurities and toxins.
Designed to fit the Whisper EX Filtration System
Traps even the smallest particles, nothing gets past this filter
I have a 55 gallon turtle tank and these work great!
However I change my filters out once a week and go threw 2 at a time and have to buy 2-3 boxes a month
However chewy is the cheapest place to buy them
I would highly recommend auto ship!
It would also be nice if they came in bulk

This are decent filter cartridges for a decent but not great filter. If you use a lot of cartridges as I do, Chewy is the place to buy them. I haven't found a lower price anywhere.

I don't like how it works .. I had to change the carbon pad in a week and the filter is a little complicated to clean it
Easy to install

These are very easy to install and seem to work well. They are rather expensive as there is no self assembly option. But there is no mess and no chore of assembling the cartridges.

Use for the best filters....

Tetra EX line. However, I don't understand why these filters are so expensive...everywhere. Can't figure that one out.
The instructions make it seem so easy that they barely give instructions

There is a grinding noise that sounds like something is stuck and the water wont filter. The thing is so awkward to maneuver that it is hard to see what is going on. Customer service did nothing but insist I should not be having a problem. Disappointed!
