Just finished filling the pool (18'x48" Intex Ultra) yesterday and ran the test with my TF-100 kit.
CH- started turning purplish around 30 drops but wasn't seeing alot of difference when i stopped at 45 drops.
CYA - filled the test tube and could still see the dot
I want to do the BBB method as a FYI.
So please tell me specifically what I need to do as this is becoming very overwhelming to me. I tried doing the pool calculator but i don't know what exactly i am reading. I need someone to babystep me through this
