Calibrate often!

[Dan1789]

Don't expect your refractometer and ph probe to always be right. Calibrate often. I just re calibrated my refractometer using 1.026 solution. It was way off. I thought my tank was 1.025. It was at 1.020 !!!! Next up is my PH probe. Just a word of caution to everyone.

My refractometer is off so often I rarely use it.

I've switched to conductivity probe, my refractometer's in the past have nearly ruined me.

Yea, I'm looking into a probe.
