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

great

great price and they work just as originals.

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

We have two filters utilizing 4 of these filters on a regular basis and the water is never clean.

Nice to have plenty filters on hand.

Great price

Muy buenos

These are great filters. The only downside is that you need to change them a little more often when you have hard water, but it still works great!

High quality

This was a great deal, way cheaper than in pet stores locally.
