GH tester doesnt seem to be working correctly.
GH: ??? - inconclusive
I've never had a real problem with my Ph, Kh ect ect. However, reciently I have been trying to raise guppies and it seems as though soft water may be a problem.
On with the GH tester. The kit says that the water should turn orange on the first drop of testing fluid and then you need to count the drops untill it turns green (the test is very similar to KH as you probably already know) But instead of turning orange on the first drop it turns pale yellow, and after the 12th drop still didn't turn green.
Is it possible for my GH to be sky high (>12) and my Kh to be low? Or is somthing else wrong?
