Adding Chlorine once a week ?Hi Guys I'm kind of new to this topic , I bought a house not long ago in Miami ,Florida with 16,000 gallons outdoor pool , I hired a guy to take care of my pool , he comes once a week to clean the pool and adding chemicals . The water is always clear , I have been using the pool with not skin problem or burning eyes. It's ok to add chemicals once a week ? . I heard most of the pool guys only do service once a week . Thanks in advance for your help .
