Top Fin CN-S Corner Filter Cartridges (6 Month Supply

These little filters really put in a lot of work.

Ehhh. It’s a filter. The price is decent and the closet place to me to but this type is 45 mins away. It keeps the water clear (amazingly so considering how little I know about tank upkeep) and I have to have them unless I want to A:) lose the tank or B:) swap to a different filter type. Since I’m not ready to do either of those things, it seems to do the job, I can by multiples (let’s face it they have to change regularly and I’m to lazy to drive 45 mins everytime I need one as well as to keep to not buy in bulk) and I’m not ready to move to a different filter type….. I guess for the time being I will keep ordering these.

Wow! Fish water is so clean I can see my fish.

Filters were intact but box was crushed in shipping.

Perfect for my 10 gallon tank with the corner filter. Good supply that I will use for the next few months. Fits in perfectly (I was scared it wouldn’t even though this is the correct cartridge for the filter) and is easy to put in. Good amount for your money too! The tetras are happy

Great filters for a great price. Much cheaper than buying at the pet store.. Keep your fish happy

Filter for aquarium

The CN-S filters have been hard to find. These are incorrectly advertised as such, however they came in as CN-L . Seller allowed return.
