I have been doing this hobby for a little while now,,but just recently got into corals,,I was advised to check my hardness level,,,(there's a good joke there) but anyhow...I bought the tester,, but it doesn't state anywhere what the level should be..all the guy at the store said, was that it should be above 12,,but how far above 12, and what is too high,,thanks for any help
