XS-13 is a control solution with no additions or alterations, and XS-14 is a control solution that was filtered, but not diluted after dolomite was added and left overnight in the solution. XS-15 is a control, where the solution was filtered, but not diluted after dolomite was added and left for 10 min in the solution.
