1 - the procedure says adjust pH beforehand. I know for a fact that adding chlorine raises pH. Also, chlorine is ineffective if pH rises above 8. How do you maintain effectivity during the process without adjusting pH?
2 - I need to maintain shock level (FC=24 for CYA=60) until OCL is less than 1 ppm. At that point, how do I get back to normal levels? It will at least 18 days (not considering the sun) to get back to FC=6.
