refractometer

[Troy F]

I just received my refractometer from Marc at North Coast Marines. Marc was very helpful throughout and the r'meter arrived very well packaged, (thankfully because 'ol Cliffy Claven kicked the hell out of the box).
I was a little disapointed when I calibrated the unit and checked my live rock tub. It turns out that my cheap swing arm hydrometer is bang on.
