thinking of doing this since I have to brush sides of the pool for small dollar size spots of green algae few times a week. I keep my FC at 5. My problem is my fill water from the tap is 140 TA . Currently I have to drop the pH level from 7. 8 to 7.6 once a week with acid. This sounds normal, am I right? I have the water in the pool down to 120 TA. I also made some homemade aerator's. Am I fighting a battle I cannot win? Do I really need to have my pool down to 80 TA to do the Borates? should I just forget adding Borates?
