### ⭐⭐⭐⭐⭐ Fast delivery, and safe for your pets.

Exactly as expected.

### ⭐⭐⭐⭐⭐ Easy to clean
*by M***R on January 9, 2026*

Clean them 3 times before putting a new one one

### ⭐⭐⭐⭐⭐ Great replacments, but you probably wont ever need it.
*by E***W on May 15, 2012*

I bought these thinking that I would have to replace them someday. I probably shouldn't have because the bio-screen on the Fluval C series is very durable and made to last! Rinsing it out works very well and so far I have noticed no deterioration whatsoever of the bio-screen. It's a good product, but you can probably save your cash and buy something else you'd want or need.
