Asked this question at the hydro store today. Apparently the meters blow. According to him the wear out and become inaccurate. Second time I've heard the liquid test is best. Go to the Hydro Store. I held off on this, sticking to walmart and the depot for awhile, but the hydro store has what you need. when it comes to the testing equipment.
