Something new about Salinty

I thought this article was pretty important.. i never knew that at different temps your salinity especially if using a hydrometer could be different.

If your tank was like mine at 1.022 at a temp of 79 thats actually a Salt content of 1.0243.. good to know.

good information

 

This can be VERY confusing so I'm going to try as best as I can to explain this.

Yes, that article is good......but it's assuming you're using a floating hydrometer. You have to compensate for temperature with those.

Most (not all) swing arm hydrometers have the temperature compensation built into them so you don't need to refer to any charts.

Most (not all) refractometers have Automatic Temperature Compensation built into them provided that when you calibrate it, your calibration fluid or liquid sample is at the correct temperature recommended by the manufacturer. Many models include ATC in the model number. That means Automatic Temperature Compensation. You don't need any converstion with the ATC refractometers either.
