DeniseN59 I am new to your site and need help clearing a green algae overgrowth from a 1972 plaster pool with 22K gallons of hard water. I have been balancing the pool chemicals for 15 years and this is our first green algae problem.
I took a sample to pool store to be analyzed, here are the results: FC =11.8, TC=11.8, ph =7.2, Total alk =130, Calcium Hardness = 819, CYA =99, phos.= 29, TDS = 5000. We have received the TF-100 test kit and are getting unusual readings: Total chlorine color was ORANGE, not yellow. Free chlorine level was not readable, because the pink liquid only turned darker pink instead of clear. The CYA level was 100+ and the calcium hardness level wasn't readable. I have been trying to SLAM the pool water with Sodium Hypochlorite 10%. My husband does NOT want to drain the pool, according to the CYA chart, I need to SLAM at 39 ppm with the liquid chlorine. How do I test for such a high level of FC ? I am so frustrated right now !! HELP !!
