Here's something else that might help. My local water supply company is two blocks away. These guys are right friendly. I told the manager that I have freshwater planted aquariums. He told me that if I ever need the water tested to just bring a sample by and he'll have it tested and then give me the results. They have very good testing equipment and they test for many things. That's very nice of him. isn't it? Maybe your water supply company will do the same thing for you.
