And for the doubting of the 3.5% This LINK from an article in the "Look Here for Answers" sticky in this forum says this:
Seawater is approximately 96.5% water and 3.5% salt, by weight. When the salinity of seawater is referred to as being 35 ppt (parts per thousand), that is the same as saying 3.5% salt.
I was starting to doubt myself on the conversion. lol |
it definitely reads in percent (%). so i want a reading of 3 and a half percent on my refractometer?
