    Hi Folks- Just wanted to see if I could compare measurements on water testing. If anyone can suggest possible sources of error I'd be interested in hearing them. Anyone that feels like posting their measurements on new water would be appreciated.
    • Water source: Distilled water from WalMart
    • S.G.: 1.026
    • Alk: 9-10 dKH (API)
    • Ca: 465 (Salifert)
    -Using ATC temp compensating refactometer
    -Calibrated about 2 months ago using distilled water at 68 degrees ( will recalibrate when weather cools down a bit)
