I ran my swimming pool for 7 months using a dedicated unit installed between the pump and filter. Using the unit ended the extreme algae growth and balancing problems that were ongoing issues over the previous 20+ years . With the unit installed, the pool water was crystal clear, soft and blue and the water proved to be self balancing. This was most evident after rainfalls, which were unusually frequentl and sometimes torrential, and our many pool parties. I added 4 gallons of household bleach (5% sodium hypochlorite) over a 3 week period of intense heat, to remove algae that was growing on the plaster walls. I.used and no other agents or devices to support the water quality.
