    Are some calcium reactor media types more potent than others? - BRStv Investigates

    Although there is a relatively small selection of popular calcium reactor media, people still ask which one is the best? Trying to truly define the “BEST” is difficult because it can be subjective based on an individual’s needs and preferences. So when it comes to choosing calcium reactor media, the decision could be made on lowest cost, size options, highest purity or where the media was sourced, dissolvability, amount of major/minor/trace elements they provide, or even just by popularity and longest history of users overall. Either way, there is definitely more information to be learned about the various reactor medias. At the very minimum, we attempt to answer the following question. Do different types of Calcium Reactor medias have different max saturation points? This data will determine if one media will provide a higher concentration of calcium carbonate over another at a given pH point and when combined with the various other aspects of the media will help you choose the right tool for the job in YOUR tank. The Experiment We have already collected some data in a previous BRStv Investigates experiment for Two Little Fishies Reborn inside a Vertex RX-C 6D Calcium Reactor. We tested the maximum saturation of the reactor effluent (outlet) solution by measuring the alkalinity concentration coming out of the reactor at the common pH set points of 6.4 and 6.8 with a very slow flow rate of 5mL/minute. So we applied this same experiment model to the two other leading calcium reactor media choices with similar size granules; the Caribsea ARM Coarse and Brightwell Aquatics CoraLazarus. The results of our experiment also give us some insight into how the different granule size and shapes affect the effluent concentration. When comparing all three, you can see some obvious differences. The Two Little Fishies Reborn is without a doubt small bits of very porous coral skeleton in a variety of shapes. CaribSea and Brightwell are both more evenly shaped and less porous aragonite media with the CoraLazarus being slightly smaller in granule size on average. pH Setpoint 6.4 After a full 24hrs of each media running at this low range pH setpoint of 6.4, the graph above shows the results from our alkalinity tests. Although the Brightwell and CaribSea seem to be very similar media types, it looks like the slightly smaller granule of Brightwell’s CoraLazarus creates more surface area making it easier for the CO2 to dissolve the media resulting in an average 5% higher concentration. We can also see the very porous coral skeletons and therefore high surface area of Two Little Fishies Reborn resulted in much higher average concentrations all around; 7% higher than CoraLazarus and 12% more than CaribSea...

  3. Do secondary calcium reactor chambers scrub excess CO2 & increase effluent pH? - BRStv Investigates

    Do secondary calcium reactor chambers scrub excess CO2 & increase effluent pH? - BRStv Investigates

    Every calcium reactor has a primary chamber that recirculates CO2 and melts the calcium reactor media, however, some reactors have a secondary reaction chamber intended to be filled with additional calcium carbonate media. This secondary or effluent chamber is then supposed to increase the pH of the solution by removing some of the dissolved CO2 and also increase the calcium carbonate concentration because of the longer contact time with the media. We put...

    Why do I supplement magnesium while running a calcium reactor? | 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 Alex De Michieli's question: "If you are dissolving old coral pieces in a calcium reactor isn’t it also going to dissolve magnesium as well? Why do you need to add extra magnesium?" So follow along as we answer today's question, provide some helpful insight, and help make reefing just bit more fun and e...
