If you could post a complete analysis, and mention the chemicals you add on a regular basis, it might help to get a better insight. Also what you do when there is an upset through bather load, weather conditions, etc.

The only chemicals that I add are ph+ (sodium carbonate) and ph-(dry acid) from pool store. This is my first season with SWCG, used to use Baquaglop. I have not yet had an upset through a heavy bather load and I really do not do anything but vacuum after bad weather conditions, I just let the extra water evaporate. My latest test results are 5ppm FC - PH 7.4 - TA 120 - CYA between 60-70 and Calcium hardness at 250.
