Our house is at the end of the water line, so the Chlorine and calcium hardness is crazy high. My dad works a water treatment facility, and DI water sounded like it would be the best choice. I don't want to have to buy a case of water just to fill up my tank. (20 gallons worth of it....)
pH-7.5 (Reading indicates between 7 and 8, leaning more towards 7)
Ammonia - 0ppm
Nitrite - 0ppm
Nitrate - 0ppm
pH - 7
