[APD] Bad Test Kit?
I recently bought a Red Sea test kit that included 2 hardness tests, General and Carbonate. I tested my aquarium (which I knew I had hard water due to scale) and the GH was 7, KH was 11. This has to be wrong??? I am an engineer so I naturally repeated my test, same results. I did a 10% water change with DI water and rechecked the aquarium the next day. Now the GH is 6, KH is 9. I am assuming one of my kits is totally bogus. Any thoughts?
