Review on Glow in The Dark Fish Tank Rocks - Vibrant Blue Pebbles for Aquarium, Garden, and More - 100pcs by Natasha Graham

I bought them for my fabulous aquarium. Wash them several times before putting them in my aquarium. And for the first 24 hours, my aquarium was milky white. Added solutions, nothing. change water. Clean the entire landscape, reset the tank. Milk again. We stayed five days. Ten fish die at the same time. I had the same fish for about ten months. Eventually I removed these stones and took the water samples and stones to a fish specialist. Stones are poisonous. Not recommended for aquariums. Beautiful but deadly
