Marina Slim Filter Carbon Plus Ceramic Cartridge (12-Count)

Perfect

Great filter. Water stays clear for 2 weeks,

These have helped me so much. I have an African clawed frog. She is picky about filtration. And makes a ton of waste. This filter is quiet and allows for a lower water level. I like that it’s skinny too. I really love these refills they are easy to use as well. Just slam them in and you’re good to go!

Good product, good price

Great

My filter uses two cartridges at a time; I can change them both six times and at this price it's not very expensive to do so. To me, this 12-count package seems like a very good value.

This was exactly what I needed for my tank. Perfect size and exact match of what came with the tank.

The Marina filter system is by far superior to most. Keeps my tank water clear and my green Cory catfish are happy in their habitat.

Fonctionne bien sure aquarium eau salée

Les filtres semblent bien faire leur travail. Reçu chez-moi en un temps super rapide.

Buen producto pero lo ideal es cazarlos en oferta, me duran 3-4 meses en el acuario siempre y cuando no alimentes con mucha comida a los peces.

Très belle économies c'est exactement la même choses que j'avais.

Guess what? So, I used to go through filters like crazy with my old brand, having to switch them out every 3 days because they were always full. But ever since I switched to this brand, I haven't had to change it nearly as often. I got this brand about 2 weeks ago, and just changed the filter today.
