awesome! Review by Vi
i just got this tester and can not believe I have been so long without it. unbelievably accurate! it doesn't only state you alkalinity is at 9.x but 9.xx, down to 1/100. you need to multiply the number it gives by .056. i'm blown away by this thing and want to get the other Hanna testers if they are this good (Posted on 2/1/2017)
