Knowzilla Posted July 3, 2009 Report Share Posted July 3, 2009 Well I went to use my Hagen GH/KH test kit and the instruction book got wet and the pages stuck together and are now unreadable, so now I am unable to do any of the tests as I have no clue how many drops to use or any other things to do the test. Does anyone have one of these test kits with the instructions intacted and are able to tell me how to do each test so I can use the kit. If anyone can help it would be greatly apprecated.

randy Posted July 3, 2009 Report Share Posted July 3, 2009 (edited) GH test Fill up the test tube with water to the white line. Add one drop at a time the color will change from pink to blue multiply the number of drops by 20 to determine general hardness. KH test Fill up the test tube with water to the white line. Add one drop at a time the color will change from blue to yellow multiply the number of drops by 10 to determine carbonate hardness (You can also multiply the results of both by 0.056 to get dGH or dKH) Edited July 3, 2009 by randy Quote Link to comment Share on other sites More sharing options...
BettaFishMommy Posted July 3, 2009 Report Share Posted July 3, 2009 i found this for you, it was someone else on the big bad web that lost their Hagen instructions too. hope it's what you were looking for! ____________________________________________________________ GH add 5ml water to test tube Add 1 drop at a time to test tube shaking after each drop until water turns blue. Multiply the number of drops by 20 to determine the GH. Divide the GH by 17.8 to determine the dGH. KH add 5ml water to test tube Add 1 drop at a time to test tube shaking after each drop until water turns blue. Multiply the number of drops by 10 to determine the KH. Divide the KH by 17.8 to determine the dKH. _________________________________________________________________ Quote Link to comment Share on other sites More sharing options...
