Deep Blue Water Technologies MP3001 Mpulse 3000® Water Treatment System - The Mpulse 3000® Water Treatment System sends 3000 to 5000 low voltage (positive and negative), high frequency impulses per second between an anode and a cathode to physically change the form of calcium. At the molecular level, these impulses apply energy to the calcium molecules to release hydrogen from the calcium bicarbonate in your swimming pool water. This action changes the calcium bicarbonate into aragonite, a calcium carbonate formation. This aragonite form of calcium is a soluble form which does not adhere to surfaces in a scaling manner. The aragonite crystals are also a natural pH balancer.
