I calculated the equivalent amount of 12.5% bleach (with specific gravity of 1.2) to the output of my SWG to determine what my daily use would be if I were switch to manual dosing. I run my pump for 12 hours per day (at a low RPM) and currently have the SWG output set at 30%. My SWG produces 0.567KG of chlorine gas at 100% output per 24 hour period.
The conversion is as follows:
4.536KG/1.2=3.78 Liters of 12.5% bleach per day at 100% output
3.78L x 12/24 x 0.3 = 0.567L (or 19.2 OZ) per day at my current pump run time and SWG output
1. Is my calculation method correct?
2. Is 19.2OZ of 12.5% bleach per day a typical amount for an 18K gallon pool with a CYA of 70-75? Using Poolmath, that's only a 1PPM increase per day.
Thanks for the help.
