Every time I've used the kit to test my CYA, I always wondered about this and decided to finally ask: The instructions say to add the mixture to the tube until the "black dot just disappears".
I'm getting a little older and my eyesight is not what it once was but if I squint and can still see the black dot, do I add more until I cannot see the black dot?
