## Customer Reviews

### ⭐⭐⭐⭐⭐ Very good filter stone
*by P***U on June 17, 2025*

A good helper for fish farming, it can cultivate nitrifying bacteria and is worth buying!

### ⭐⭐⭐⭐⭐ Good product
*by E***T on August 1, 2025*

Nice big box with lots of surface area. Includes a mesh bag.

### ⭐⭐⭐⭐⭐ It Just Works!
*by H***T on December 16, 2024*

It's hard to write a review for something as simple as aquarium media but it just simply works. It doesn't make any bold claims like denitrification but as the ability to house beneficial bacteria it works perfect and is priced very reasonably to fill a sump or a large canister like a FX6.
