8/9/15 we added Dichlor to get our CYA level up since it had been about a month. Tested after a pump cycle and CYA was 37 (right between 35 and 40 on the tube). Today we did our weekly testing and I thought ok let me test it for giggles. We've only used 8.25% bleach since. It's at 50 and honestly, it's likely more like 53 or 54. I couldn't believe what I was seeing.
There wouldn't be anything else that would raise that right? And oddly, we added about an inch of water right before testing today so I'd have thought that would lower it since I was "diluting" the water.
