Extremely low salinity Updated!!!

The problem I encountered was that the paper instructions said to use distilled water for calibration; yet the calibration fluid had different directions on the bottle (which i didn't fully read until it was too late).
Distilled water = calibrate to 1.000
Calibration fluid = calibrate to 35 ppt (or 1.026)

So I used the fluid and calibrated it to 1.000 instead of 1.026 (35 ppt); and threw my readings out of whack.

I was worried about the fluid because when it arrived (via UPS) it was frozen; therefore i wasn't sure if it could be trusted for accuracy.

So far the corals seem okay. I just my readings again and it has gone from 1.035 to 1.033 overnight; so slowly but surely its going back down (due to raising my ATO float switch). Another water change later today (with approx. 1.020 water) should help.
