Hello Reefers,
I have a Marineland refractometer and I'm having to double check the calibration everyday. I usually check it in the mornings and by mid evening I'm finding my self having to recalibrate it.
I calibrate it by using RODI water. I'm using the same container of water as I used during the morning. My source is my auto top off water next to my aquarium.
The temp stays the same in the house with the AC on.
Should a refractometer have to be calibrated this frequently or should I invest in an Automatic temperature compensation.
Is this my problem? What are your thoughts.
It's usually off by 1 point.
Thanks,
Christopher
