Refractometer question

[crabbychris]

My dad just told me that he has a refractometer that he uses for work to test specific gravity in batteries. Can I clean and use this so I can do hypo in my tank? Are all refractometers the same. Sorry I don't know anything about them.

no, not all refractometers are the same. Some measure the sugar content of alcohol. Others measure the acid in certain products... yadda yadda. The're not all the same.
Go ahead and get you a $45 refractometer from the two doc's website - you'll never look back.

its a lot safer if you buy your own.

Eh, they make 'em for beer too, better get an aquarium one with atc off the net. Try it and tell us what you get though.
