    BRStv Investigates: PAR & Spectrum Testing for Effective Refugium Lights

    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! We have had numerous reefers ask us to test the Black Box LED lights that are available direct from China, and only cost around $100. We were a bit hesitant to test them since was a hard one to publicize because many manufacturers don't like the Black Box LEDs, but there are also a good share of people that have used them with great success, so we figured lets put them to the test! Now, can you grow coral and maintain a reef tank with a $100 LED? The simple answer is yes. However, if you expect it to perform like an Ecotech Radion, or AI Hydra, you will be disappointed. We have tried a few different versions of China LED aquarium lights and a majority of them are built the same, lacking an actual heat sink, non-UL approved power supplies, low-quality LEDs and

    BRStv Investigates: Refugium lights and chaetomorpha testing, taken to the next level!

    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! In this episode, we are putting refugium lights and chaetomorpha algae to the ultimate test in a real reef setting. We want to see if an appropriately sized refugium can help manage nutrients and also keep nuisance algae from growing in the display tank that are lit by a single Kessil A360WE LED light. As always we had our control tank, and then we lit the other three refugiums with a Kessil H380, Kessil H80, and a standard $5 compact fluorescent light that you can get at any local hardware store with a clip-on reflector. We then added equal sizes of chaeto algae to each refugium and let them grow. The display portion of our A/B test tanks housed cured live rock along with a couple of fish that we fed whole mysis shrimp for a real world setting. For results,

    BRStv Investigates: The best refugium light test is complete, and what is coming next!

    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! Today we let you know what our ideal lighting choice is for a refugium and why. We put a handful of the best selling refugium lights to the test for the past couple months, documenting the growth rate of chaetomorpha algae and the ability to consume nitrates and phosphates compared to a control tank. After reviewing the results along with the lights spectrum and PAR levels we came to a conclusion for what our ideal refugium light should be. So what is next? We are breaking out the A/B test tanks to put refugiums and chaetomorpha to a real world test. So make sure to watch today’s video to see what we will be up to next. *Legal Stuff* The purpose and content of this video is to provide general information regarding the products and their applications as p

    FAQ #45: Can a refugium be too effective at absorbing nutrients?

    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 googlereallysucks question: "Can macro algae in a refugium drive nutrients too low?" Overall a refugium is very unlikely to strip your tanks nutrients to a level that is too low. When it comes to nutrients in a reef tank, a majority of people are only referring to nitrate and phosphate, but they are very far from the only important nutrients found in a reef tank. Refugiums are usually packed with chaetomorpha algae that in some systems can grow very quickly to the point that it may concern some reefers that it may be absorbing too much nutrient from the tank and possibly starving the corals. 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. If you would like to join the larger conversation

    BRStv Investigates: Can Chaetomorpha in a refugium be the ideal reef tank filter?

    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! Today we are taking a look at growing chaetomorpha algae. There has always been a debate on how large of a refugium you may need, and if they even work as your tanks main nutrient export system. We are keeping an eye on the pH, Nitrate, and Phosphate levels in each tank while we feed and add nutrients to each tank to see how the algae works in a refugium type setting. We have the algae growing under different kinds of lights that are marketed with a spectrum to grow algae like the Kessil H380 and the PAR38 Refugium LED. We have been growing the algae in test tanks for the past 30+ days monitoring their growth and tracking their ability to lock up nutrients. We are going to keep running this test for a little while longer and make sure to follow along while we

    FAQ #29: Should I run my protein skimmer before or after my refugium?

    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 Raees Usman's question: "In a sump, which one should come first the skimmer or refugium?" I believe the skimmer should be first in most types of fuge installations and that's based what they are actually trying to remove. They are removing different elements from the water and for the most part not really competing with each other so it shouldn't matter all that much, with a couple of common exceptions. A protein skimmer is designed to remove organic waste "before" it has a chance to break down into phosphate and nitrogen compounds. Essentially we want to remove the compounds of fish poop and uneaten decaying foods as small particles or resulting dissolved organic compounds. However a skimmer is far from one hundred percent efficient at this, I have seen some articles that suggest a typical

    FAQ #17: Is it worth running a refugium on a Zeovit tank? | 52 FAQ

    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 John Owen's question from Week 48: “I would love to hear more of your thoughts of using a refugium with the Zeovit system. Most everywhere I've read says that the algae will end up dying. I was wondering how the BRS160's refugium fairs on the system." The quickest answer is the fuge plays a pretty limited nutrient reduction roll on a zeovit tank where there is almost always going to be very limited nutrients. Because of that, nutrient related algae or other related issues are a pretty big rarity. This has been true in our case as well. Even though we are pretty heavy feeders, the tank tests zero phosphate and less than one nitrate every week and I am pretty certain it would even without the fuge going. The ball of chaeto does grow but we have yet to harvest any, so technically I would s

    Week 27: Refugiums - Utilizing algae for a thriving reef tank | 52 Weeks of Reefing #BRS160

    Welcome to Week 27 of 52 Weeks of Reefing! This week we are exploring how we can use algae to our advantage in the reef tank to help combat nitrates and phosphates...with refugiums! Refugiums are essentially a location in your tank (usually the sump) that allows you to provide a safe haven more micro fauna, as well as grow beneficial macro algae like chaetomorpha or caulerpa. There are a fair share of different types of refugiums out there today, with an equal amount of opinions on how to run them. The traditional refugiums with algae and/or live rock rubble are the most popular and effective in my experience, and some of the easiest to install and maintain. An older technology that is starting to gain more ground again is the algae turf scrubber. This is essentially a very efficient refugium; algae is grown between two light sources on a medium with water flowing past it and then periodically harvested. There are also a few more creative and unique options out there
