Review on 🐠 Tetra Carbon Filters: Perfect Fit for Whisper EX Filters in Aquariums by Jennifer Wilson

If you have a filter that requires these Tetra Whisper EX carbon filters you can definitely buy them here. I have searched many websites and local stores for this particular product and Revain has the best price by far. Each of my filters on my 55 gallons requires 2 of these, so one pack is enough to replace my two 22 55s. However, note that the filters also contain many of the good bacteria your fish need, so I never swap out both at once, instead swapping out one side and after a few weeks or even months (depending on how dirty they are) one others from . Great price and I will keep them on my 'save for later' list so I can easily buy them again when they run out. Many Thanks.
