NYOS Reef Cement - 500 ML vs Luffy 10 Betta Mineral Balls - C...

This product is not that great. Let it sit over night and it still cracked. Crumbles in water and clouds entire tank. I let my reef drying for 24 hours to have better results.

The bag i recieved is closer to 2 inches by 3. My shrimp never use these in the aquarium.
