salifert kh expires 3-2010
ap phosphate 64A1204 (lot number .. I guess expires 12/04)
ap ph 2880105
ap gh 58A0304
ap kh 59A0703
salifert po4 12-2006
if these lot numbers are the dates, then they are no good I guess?
I have good dates on all my salifert tests but they are ammonia, nitrite, nitrate, kh, and phosphate. I just did the salifert phosphate and it reads 3ppm but that is where the scale stops.
btw thanks spar for answering so many of my questions. I really do appreciate it.
