    Hi all:
    I'm helping out a colleague with a temporary cold marine set-up (ie 4 gallons of chilled water to keep some periwinkles and hermit crabs from Long Island Sound alive long enough to show to some kindergarteners). My question is about the Instant Ocean Marineland swing-arm hydrometer I have. I know that it is calibrated for warmer water, so how do I adjust my reading for colder temps?
    Many thanks!

    Need to use temp/salinity conversion chart, like one below.

    Need to know for what temp your hydrometer is calibrated for.
