## Customer Reviews

### ⭐⭐⭐⭐⭐ Satisfied
*by E***. on April 11, 2021*

The rocks we ordered were rather large for our smaller tank but after buying cheap rocks to save on overhead we made due. These do not disentigrate and leak phosphate like some do. I've had no issues with GHA after install

### ⭐ Was not shelf rock
