Review on 🏝️ Special Grade Bimini Pink Reef Sand by CaribSea Arag-Alive - 20-Pound Option by Christine Wilkie

I use this 20 lb Arag Alive sandbag to help with live sand filtration in a mini container that has been repurposed for this sand. 20# sand provided about a 3 inch deep surface in this container which was then placed in my open sump in my hydroponic grow tray. in my case it is a must. Sand provides a great habitat for nitrifying bacteria and is excellent for this application.
