Thanks for the info. I ordered my refractometer from north coast marines, and should be here tomorrow. Had ir rushed delivered since I need to do hypo on a q-tank.
Thanks Again for all the help.
I bought mine from them about 3 months ago - ick and my purple tang lol - thing works like a champ - prolly the best 80 bucks I've spent in this hobbie!
I ordered one on ---- and recieved it today. I've used it once and absolutely love it!!! Readings from my swing arms are off worse than I suspected though . I definately recommend the purchase to anyone. Well worth the money!!!
