I’m at NSA, to Grace and Olivia went to Manchester.

Today they proved they were listening for the past three weeks when I was at Manchester training them! They’re rockstars. #success

• Water chemistry sampling: 1L grab samples and bottle samples
• I had them do the standard curve first after Hollie gave me the same advice
• Rick’s probe was unavailable, so they used the refractometer to measure salinity in psu instead. I think the refractometer is reading values lower than either probe would because it’s not as precise.
• There was a communication mix-up over the phone, so they accidentally discarded the original water samples before measuring salninty with the refractometer. I told them to take new samples and measure salinity, since I don’t expect salinity to vary greatly in the tank.
• Cleaned filters
• Bleached algal lines

Here’s the data they collected:

Grace said she didn’t see any of that weird stringy stuff we saw last week in the tanks, so maybe the problem’s solved? Fingers crossed.
