I'm new here and I'm not sure where to start this thread. Also, I'm sure that many of you know that a good water testing kit is a good thing to have. After a 25 year lapse, I decided to set up an aquarium once again. My fish were dropping dead as fast as I was buying them. I thought our well water was fine for the aquarium but I bought an API freshwater master test kit. What I immediately found out was that our well water was extremely alkaline. I tried fish that could tolerate the high PH but was still losing fish. Just one or two a day. Now I get all of the aquarium from a spring that gushes water out at the foot of a mountain. It test 7.0 and has solved the dead fish problem. BTW I had tried natural drift wood but it wasn't bringing the PH down. I'm lucky to have the spring a couple miles from home.
