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

Perfect for turtles

Great price for the amount given

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

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

Did you know that these can come apart? I rinse off the crud and empty the used bags. I then refill with Marineland Diamond Blend Ammonia Neutralizing Carbon. I will probably reuse the bags 3-4 times then trash for new.

Great item, great price

Excelente inversión. Cada 45 días ordeno 3 cajas!!!

We use these in our duel fish and turtle aquarium and theyre great! They are easy to rinse in between changes, if something gets gunked up, and we have them shipped regularly to us. They definitely help keep our water clear in our tank.

Great value for the price.

I always buy this item for my mom because she has 6 turtles. We buy it often because she loves the product and is simple to assemble. The product brings 4 packs of 3 filters, but this time around we only received 1 pack of 3 filters and her card was charged for full price. We are both very dissapointed and the only choice is to return the item and get a refund, we dont want th emoney back we just want the full product, like we always get. We are happy with this product. I hope Tetra sees this review and does something about it.
