I read a post a few weeks ago where someone mentioned that their lfs has a tester that you put a sample in and it gives a printout of all the specifics, ca, alk,mag,, ph, nitrate and so on. Anyone ever seen one of these? Person mentioned they charge around $5/test. Curious to figure out what it is and can't find it online.
