Calibrating Instant Ocean Hydrometer

Post by greenspottedlover »

Yesterday I bought a Instant Ocean hydrometer. Last hydrometer I had said it should be filled with fresh water for 24 hours before first use. This one says no such thing. Does a Instant Ocean Hydrometer have to be calibrated?

All hydrometers/refractometers should be calibrated with Pinpoint solution.

I think the OP means "seasoning" and not calibrating.
