With the rising popularity of using Chloramine (Chlorine + Ammonia) as a disinfectant in municipal water supplies, the risk of contaminating reef tanks with this harmful chemical rises. Standard, low-cost carbon block filters used in a majority of RO/DI systems simply are not designed to remove these toxic Chloramines.


In this BRStv Investigates, Randy revisits the BRS Universal Carbon Block filter test using better technology with our brand new Hawk CL17 Chlorine Analyzer. Just as we found in our previous carbon filter experiments, using the right tool for the job goes a long way in ensuring you get the most out of your RO/DI system and ensures those harmful Chloramines do not make their way into your aquarium.
