Coralife hydrometer was reading 1.023 used to set tank up. Today I used an Instant ocean hydrometer to check my tank 1.028. Took some water down and had Beaver take a look at it 1.030= I walked out with a Refractometer.

good deal. To be absolutely sure, test your refractometer against the standard Randy Holmes-Farley made (for the most accuracy).

Why do we park in a driveway, and drive on a parkway?
There is NO SUCH THING as a hot water heater.
