Actually the rain is having a major affect on my pool. My new TFP method is called rain and drain. Every afternoon I drain 4 inches of water off. Every night it fills back up to the top of the flagstone. I've proably taken 20 inches off in the last 2 months. My numbers run all over the scale. I even put some tabs in the tube just to help with chlorine and bring cya back. Calcium is down again. but it still looks perfect. How is everyone else handling this?
