"My plants are growing absolutely amazing!! It’s in pebble-like format so no need to cap the soil with anything if you don’t wish to!"
"even after rinsing repeatedly, water still runs black. it does great for plant health, but makes the water in my tank black even after rinsing and months of cycling in the tank. i am very disappointed in the product."
