Reefing newb
Hey i recently ordered a refractometer on ebay and am waiting for it to come in. Until then, i purchased a new hydrometer to replace the old one my friend gave me. I read somewhere that you need to let water sit in them for a certain amount of time to break in? Is this correct? Also i borrowed my friends refractometer tonight and compared the 2 readings which are only about .001 off. So am i good to go with this estimation or do i need to let water sit in it for awhile since i just got it?
