as far as using the pH down. i think mine says something similar. it's bs. i end up using like 35 drops for a 2 1/2 gallon container. and about 14 for a 1 gallon container. granted these might not be the same brand, they should be similar. my tap pH is WAY over 8!

but it is important to get you pH down to 6.3 - 6.8. don't forget that many nutes are neutral and will drop you pH a little bit.

just my $.02 cents.
