### ⭐⭐⭐⭐⭐ Review
*by J***M on 31 October 2020*

Bought the large brick as I have used MarinePure for years. I used 3cft of it in my koi pond shower and used it in multiple fresh water set ups as well. I ordered this for my reef tank and as expected it is a great biological filtration choice. It does its job due to its porous design however it doesn't handle rough shipping well. My brick came broken in half. It doesn't look great but it lost none of its function. I would buy this over and over again in figure set ups without a single concern.
