I believe we had our water tested when we moved in to our house about 9 years ago (my wife worked for a water softener company at the time) and I don't remember the results, but I remember there wasn't anything alarming as far as our health. Not sure about aquarium health, though....maybe I'll have it checked again..albeit a little late.Well the big question is that you are coming from a Well, which in which you could have all kinds of other dissolved solids. Did they test for anything other than the basic 4? IE Did they test for Calcium, Phosphorus, Magnesium or any other metals? I know that here locally wells have an issue with arsenic as well.. Not saying your gonna have a problem, but the potential does exist.
Congrats on getting it going though and make sure you test your wet/dry several times.. Its a good thing that you haven't had an overflow yet, but I made a slight miscalc and overflowed mine.. :eek3:
I have close to an inch to the top of the tank, so I don't think I have a danger of an overflow if I lose siphon. I'm more worried about killing the pump or leaky fittings or something...
