remove previous calcium scaling from pool surfaces?
Well, it depends. If the current scaling is a result of years of neglect, it would take a long time to remove such calcification with the mPULSE 3000. However, if the scaling is fairly recent (30-60 days), we have seen instances where the water level was raised above the scaling and the calcium was eventually removed. The time and success rate of this can vary from pool to pool.
