Today on BRStv, we have a brand new episode of our series, BRStv Investigates. In this series, we explore popular reefing theories, products, methods, and what the manuals are missing, with a focus on putting them to the test! This week we take a deep look into PAR sensors and give you a little look into how they work. We put some of the top industry leading light sensing devices head to head under some of the most common light sources resulting in some shocking realizations. So follow along as we investigate today's question, see what kind of issue we stumbled upon, and find out what kind of PAR Meter we suggest using for your reef tank. Be sure to watch and keep an eye out for future episodes as we test spread, PAR, coverage, efficiency and more! *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.
