After a water change I refill the tank with RO/DI water and let it sit with a power head turning the water.
About 2 days before I want to do a water change I add the IO salt and a second pump to mix the salt. The next day I test for Ca and Mag. I then calculate the required dosage of Calcium and Magnesium to bring the batch to the right levels. The following day I pump out my sump and replace the water with the now completed 57G mix.
I then pump 57G of RO/DI from my water top off tank to fill my mix barrel for the next change.
