Today on BRStv, we have another episode of BRS 52 FAQ where we answer all of your frequently asked reefing questions from our popular 52 Weeks of Reefing series. This week we are answering Rob Fern’s question, "Why don't you put sand first, so the rock doesn't contact the glass directly? Would it be safe to put something between the glass and rock? Like lighting crate?" Unless you have an accident and drop a rock onto the bottom of your glass tank, the chances of the bottom breaking is pretty slim. In the years we have been working with aquariums, and the thousands of reefers we have talked to, we cannot recall one occurance of rock breaking through. Our biggest recommendation is to make sure you have a stable rock structure and use adhesives to bond the rocks together, preventing a rock avalanche down the line. Putting the sand in first, then the rock on top of it usually leads to settling of the rock over time, leaving you with an unstable structure. If you do want to add some extra insurance to your glass bottom, there are options like starboard, PVC sheets and more that can be added so your rock doesn’t rest directly onto your glass. So follow along as we answer today's question, provide some helpful insight, and help make reefing just bit more fun and easy for you and your tank. *Legal Stuff* The purpose and content of this video is to provide general information regarding the products and their applications as presented in the video.
