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 Patrick Egal's question from Week 25: The Rollermat has max flow rate recommendation of 600 gph. That implies 3.75x turnover per hour for this 160 gallon aquarium. What flow rate is your return pump putting out? We’ll touch on a few different reasons why this is, and finish with a few quick tips to help you with planning your plumbing setup for the Theiling Rollermat. 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.
