Today on BRStv, we have a brand new episode for 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! Join us this week as we are going to be taking a look into how much light do typical screen net tops block, and does the size of the openings on the screen make a difference? We test two different sizes of screen that are very common for tops. Screen net tops are great at keeping your fish in the tank while allowing a large majority of the light through the screen, but there has always been a concern of how much light is actually being blocked? So follow along as we investigate today's question, provide a little insight into screen net tops, and help make reefing just a bit more fun and easy. Want to join the discussion? http://www.reef2reef.com/threads/diy-screen-net-tops-tips-tricks-and-pics.290457/ 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.
