I received my TFT Test kit today. Super fast service! I only just ordered it the day before yesterday!
Anyway, I need some clarification on the CYA testing instructions. It says to "Fill the Red-capped CYA mixing bottle to the bottom line with the pool water. Now, fill the bottle to the top line with R-0013." There are no lines on my bottle other than the label. Are those the lines being referred to? The bottom and top of the label? I just want make sure cuz I don't want to waste any of my chemicals if I don't have to.
