Today I plan to start the process of reaching 50 ppm borates. Since this requires several alternate additions of borax and muriatic, and considering that these chemicals force pH in opposing directions, how long should I wait between subsequent additions? Normally I would wait several hours, but I would like to accelerate this process due to time constraints (I only have about 3 hours to work with in the evenings). Also, do borates evaporate? I know they don't get "used up" but I wasn't sure about evap.
