THANK YOU ALL. I'VE RETURN THIS. THEY GET ME BACK 80% MONEY ONLY BUT I THINK BETTER THAN KEEP THIS. SO I'LL BUY ANOTHER ONE. PLEASE LET ME KNOW WHERE I CAN BUY THIS FOR $20.00. THANK YOU AGAIN.

Thank you. So If I want to put salt that measure around 1.023 / 5.82 then I think I have to measure my refractometer on 5.82. Mine has only 0-30% Brix scale. Do you think I am right?

Thank you. But I don't want to buy any another one.

My link I bought this refractometer through Amazon.com and yesterday I've got this. When I test it I realized that it is unusual but something different diameter. Look very simple but I don't know what diameter says. Please let me understand it. I just need how much salt I need to put my tank. :'(
