I have decided that Earth Juice pH products are Shit in a bottle. I am having tons of trouble with my pH. I'm gonna dump the tank again, what a waste. I am going back to regular pH up/down again. It's really pissing me off. It took me a whole day adding a capful at a time, and got it to 6.3, one capful later, it's down to 4. It is not behaving logically. One capful takes me from 6.8 to 6.4, then one more capful takes me to 4? it's insane.
