CalMag+ - A supplement you add to your water to make up for the minerals removed during the r/o process.

R/O - Reverse Osmosis - a filtering system that removes almost everything but the H2O from water. The water you bought at pricemart is r/o water. (Doesn't it feel good to know that you did at least one thing right? :thumbsup
