Ok, I went back through and refreshed my BBB method. It's been a long winter and this will be my second summer of BBB It looks like after I get my pH above 7.2 I need to get my FC up around 10+ to "shock" it. So about 6 gallons of bleach all at once at night? Retest the next morning and add another 6 if FC is not above 10 yet? And keep the FC above 10 and pH above 7.2 until I can see the bottom? I'm guessing without any CYA my "maintenance" doses of bleach having been doing anything.
