Top Fin Retreat RF-S Filter Cartridges (Small) Refill for Desktop Aquariums with Small Retreat Filters - 8.1in x 1.9in (6 Count)

We bought a Betta tank from PetSmart, and needed new filters. Found these and they work d great at a fraction of the price. Will buy again when I run out.

The product itself is great but came in a destroyed box. Thankfully the filters look to be intact

Just perfect. Super easy to put in place and keep our thank in shape. Collects all the residue of food and waste on water and keep a crystal clear look with no to much work. Great product !!!

For my fish tank

Fits perfectly, does a great job and the price is right!

I have been looking for these filters in every single pet store I could find and amazon seems to be the only place that carries them. Very happy with purchase they work great.

Its perfect size and exactly what we needed. No complaints.
