Dracko's 55g Reef

TDS checker may need calibration occasionally. Maybe bring water sample to LFS with meter and have them compare it to theirs.

Vertical mount is best for DI, and I would definitely not trust distilled water to be pure enough for calibration.

No, I did not use it for calibration. It came pre-calibrated. I used it to see if it was reading in the range it should be for distilled water, and it did. Will hang that unit vertically and see what happens.
