Its running at 100% , what will be the problems. One tablet a week seems to be maintaining FC.and CYA. as I understand, a targer of 75 CYA is just to help chlorine stay in pool because of using a SWG any other method , 50 CYA is good and I have been able to maintain both. If im missing something. Please spell it out. My pool right now looks just as. Good if not better than the pools in my neighborhood that are being maintained professionally.
I have been told that though CYA is important to keeping chlorine in the pool, the higher CYA gets, the less effective FC is at sterilizing the pool. This is a fine balance between CYA and FC. At least for the rainy season, II feel I have found that balance that works for my pool.
