Tetra ReptoFilter Filter Cartridges, Medium, 12 Total Cartridges (4 Packs with 3 per Pack)

Amazing, my tank looks clearer than it has been in months

great

We keep a stock of these as we change the filter regularly. I keep this on my Wish list for my daughter’s turtle tank.

Saves a lot. Beats the pet store prices

I use them in my snakes fake rock waterfall filter thingy. They filter as promised.

I was extremely happy with the number of filters, you get in this order. It definitely was less expensive than buying them at Petco or Petsmart. I will surely purchased them again!

Affordable

Timmy the Turtle loves these...

Nice to have plenty filters on hand.

Just as expected!
