Aquarium Advice FINatic
I found a couple refractometers online. My question is this:
Some say they are for "aquariums" and measure in PPT (parts per thousand) and also SG (specific gravity)
I have also seen some that measure solution rages of 0-32%
Is there a difference? Or should I purchase one that say for "aquariums"?
I would think that they would all be the same. Some input would be helpful here if anyone can help.
TIA
