If you’re planning on disinfecting your water with bleach,,,,,, I’ve been in the water biz for almost 30 years. Public water supply. We use Sodium HyperChlorite to disinfect the water. SHCL is bleach. The stuff we use is the same as pool shock, 12.5%. Household bleach is 6,25%. It’s important to know that SHCL/bleach starts to deteriorate the instant it’s created. It must be stored in a cool, dark place, and that still won’t stop it’s degradation, only slow it down! Studies have shown that, by the time a home consumer buys bleach at the store, it may have dropped to 3%. So,,,, don’t store bleach for too long, and count on it’s effectiveness. Buy a color wheel chlorine tester. Cheap! It will tell you when the water has been safely disinfected. Me? I keep the “pool shock” strength stuff around. The crystalized product might be even better, as you could make you own fresh SHCL whenever you needed it. I’m not sure about that, as I’m a potable water guy, not a pool boy!
