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

That it was fast delivery, there wasnt anything I didnt like

I only rate these poorly because the filters they fit in are trash and unfortunately I am not Oscar the grouch SO THEREFORE I DO NOT LIKE THEM.

Work as they should!

Fast Shipping, great filter, no issues, cheaper then buying at the store. Thank you.

Perfect for turtles

Great price for the amount given

Great value & quality product!

I love when our turtle is happy- these filters are quiet and clean and great for odor control

For keeping turtle tank clean
