very simple, i found the hardest thing was to flick the right amount of water out of the cl/ph test block... i found a kaflink and a pap to get it to the line is the best way. The more i test the water the more i feel relaxed doing it. I even did a couple tests twice just because i wanted to see if i got the same answer twice.
I use a squeeze bottle from Walmart (similar to the picnic catsup and mustard bottles, but clear), and get it right on the marks every time. Cost me $1.99 for two of them, IIRC.
