Calibration

[BKLYN651]

I never checked my refractormeter in the 10 years I owned it. I have been keeping my 55 and 20 gallon reefs at 1.025 with no problems. I finally Purchased a bottle of Brightwell calibration standard to check my refractormeter. Found my SG to be 1.022 Do I leave as is, or increase to 1.025

I'd double check the calibration somehow (maybe a DIY), but if true, I'd slowly raise it.

I would raise it SLOWLY.
