How often do you calibrate your refractormeter??

My vertex unit is touchy too. I calibrate with a 35ppt solution every time.

I never calibrated mine since the day I first got it which was prob a couple years ago...big mistake. Just recently had a buddy test my water and it was at 1.022 even though it would show as 1.025 on my refractometer. Who knows how long it's been at 1.022??! I've had a bunch of nice corals die and gave up on them because I couldn't figure out why at that time... Now I will calibrate mine after a couple uses. A bottle of proper calibration solution is only $5 so it's worth it.

I'm with u guys. Pretty simple to keep calibrated so why not? The less fluctuation my tank sees the happier it will be as far as I'm concerned.

hmm maybe it's time for me to calibrate mine....
