Refractometer

[Troy F]

Northcoast Marine sells them down in the States. Try searchin reefcentral with refractometer and Northcoast as search words. You'll get the address quick enough. The guy running it is realiable. My swing arm is within .001 of my refractometer. Maybe you'd like to buy it for $100US [img]images/smiles/icon_biggrin.gif[/img] [img]images/smiles/icon_wink.gif[/img] .
