Tetra Carbon Filters 2 Count, For aquariums, Medium, Fits Tetra Whisper EX Filters, Tetra Whisper EX20 Carbon Filters, Medium, 2-Count

Fits great into correct tetra unit(s) and does a good job filtering even the dirtiest aquarium water.

Our filter needs these carbon cartridges and found these at a great price.

Work great, good quality for the money.

these are easy to install, and by the next morning, the water in the tank was crystal clear

I don’t think the quality of the filter is the best especially it don’t last a month. It’s been two weeks and I had to replace them. Meaning the tank has to be replaced as well but I noticed it fast and changed the filters before having to change the water out also.

I opened the (sealed) box and only got 3 filters. First page of reviews and somebody else had the same problem, so this is probably pretty common. Im sure Amazon would refund no problems, but I also realized I ordered a size too big - so rather than deal with all the hassle I just made them fit, dealing with it for now. But again - check your box as soon as they are shipped. Dont wait until it is too late!

The pads are ok. Dont think I like the filter much. The old wisper was better. Dont upgrade

great filter for great value.

A+

Work great and lasts about 2-3 weeks before needing replaced. The only con is that they are a little on the expensive side.
