My salt water system just will not keep up and I have to add chlorine weekly. I am at about 50 on cya which is a little low I know but still seems I should be able to keep up. I even returned my old swg for a new one thinking it was defective but new one is the same. I keep the pool spotless from debris and even run boost cycles which will raise it some but right after that when it goes to normal cycles I loose my chlorine in a day or 2. please help I would hate to goto a chlorine pool.
