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! Creating a gyre flow pattern in a reef tank is simply a circular path that the water exiting the pump travels in, around your tank and back into the pump. The Maxspect Gyre series of pumps is well known for creating this style of flow, with their nontraditional propeller design. The Gyre pumps put out a sheet of water, and with a majority of the water intake on the bottom of the pump, you can mount the pump relatively high up in the water column without having to worry about a vortex being created and making microbubbles. But we also wanted to know, if other types of pumps can create a gyre pattern in a reef tank? We pulled out a few other popular pumps like a Vortech MP40, Tunze 6085, and a couple Hydor Koralia Gen 3 pumps. After spending a day with wet hands and testing out each pump, we found that a couple of them had the potential to create a full blown gyre in a reef tank where others simply did not have the char characteristics required. After testing them in our Reef Savvy test tank with a beautiful coral insert from Living Color Aquariums, we put the pumps in the BRS160 for a real world application. Make sure to watch, to see what pumps we selected for the BRS160 and how the others faired! Next week we have another excellent episode of BRStv Investigates, so make sure to keep an eye out for it. We have a bunch of tests currently running that we are very excited to share with you! *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.
