A few hours ago I went to my lfs and bought 25 pounds of premium Fiji live rock, RO DI premixed saltwater and some live sand. It's startin to clear up a little bit so I tested the salinity. I used an instant ocean hydrometer and the needle is against the stopper at the top!! It's a brand new hydrometer. Is that why? There were no bubbles or anything on the needle.
