hello i bought a aquarium pharmaceuticals (doc wellfish) KH test kit yesterday and just wanted to check to see what im exactly testing for. i want to read alk. my tester turned yellow on the 8th drop,showing me 8 degrees dkh :S or 143.2 ppm KH and this kit also does GH but the chart is no different. so,GH and KH are the same? and can i check alk with this? and am i ok? thanks
