I am tring to maintain my pool with as little chlorine leval and shocking as possible. I have a nature 2 system that states .5 ppm chlorine and shock monthly or for non chlorine systems, shock once a week with non chlorine shock. I saw the thread on the benifits of borates so I have decided to bring my borates up to 50-60ppm my question is how much clorine should I have to run and how often should I shock? Do you think I could run at .5ppm clorine and not have to shock? Do you think I could saftley run a no chlorine system and shock like every other week? please forgive me I am new too pools.
