## Customer Reviews

### ⭐⭐⭐⭐⭐ Will add to all systems
*by R***R on June 26, 2023*

Its amazing how much better these work than my fill and drain beds alone. I bought them for an isolated system that feeds my in-ground corn and doesn't have a fill and drain bed system attached. I put in the same ingredients but the system with these things obviously works way better.I plan to add a small bio reactor tank with these in it to all my systems.They are relatively expensive though.

### ⭐⭐⭐⭐ Work very well
*by C***R on May 9, 2024*

So far the filter media has worked very well. once they have been in the system for a while they have become almost neutrally buoyant which makes cycling them around easy with a small amount of air. he only reason that i gave them 4 stars is the cost. when you need a large amount the cost can become prohibitive. If money is an issue with setting a large system other alternatives may be a better route.

### ⭐⭐⭐⭐⭐ Happy Koi
*by L***A on November 16, 2017*

The filter media appears to be working beautifully. I am using the media in a pond in a greenhouse with Koi and the water is very clear.
