Hello. Awesome page by the way!! Looking for some help with my chlorine levels. Pool was finished late August 2015. Always had trouble keeping chlorine levels where they need to be. We recently emptied the pool for an acid wash and polish, and upon refill noticed the chlorinator was full of air after shutting the pump down. Long story short found it to be a leak in the filter housing. After solving that and the chlorinator stays full of water (thought this was the issues). Well now that the chlorinator stays full the chlorine levels keep dropping. My CYA levels are good (about 45), I have approx 65 ppm of borate in the pool, and the usual stuff (stain and clarifier, calcium perfect). I have to shock it almost every other day to keep it at about 3 ppm chlorine. I do shock at night and my water is crystal clear. Even after all this my chlorine almost doesn't show up on my dropper test, and once a week I have tested at pool store where again it's always low. I use Clorox shock bags, and have recently (last week) started using the BBB method. I just dumped half a gal of 10 percent bleach and will check tmrw for chlorine levels. Any ideas why the chlorine level struggles so much. Again I use tricolor picks and run the chlorinator on max with the pool running 7 hours a day. Worried with Houston summer almost here, I will come home to a green pool one day. Thoughts? Questions? Thanks!!!
