How often do you calibrate your refractormeter??
 

I have used have my refractormeter for nearly a year (10 months) and never thought of calibrating it because it seems to work well..

How do you know it's time to calibrate or how often do you calibrate it??

on google, some says they calibrate every time you use, others say they have not calibrated it for over 2 years..

mabie once a year it seems to stay perfect tho

every few water changes i check it.. Once a year scott? really, come on man lol

Lmao or when my corals look funny and everything thing elts checks out :p

People calibrate these things?? oh....lol

haha that's what I thought at first.. lol

I don't do many water changes.... But once ever few months! Lol it only takes a second!

Ya, but that little bottle of calibration fluid dries up the first week :)

Lol oh it's been a long time! I forgot how much fun this site was!

Never have maybe I should check it lol.
