You are supposed to throw it in the trash and buy a refractometer instead. :)
I don't know anyone that lets the hydrometer sit for 24 hours. Most people just dip it in the tank and take an instant reading. They are very innacurate though, even right out of the box, a half dozen brand new ones will give you a half dozen different readings with a very wide spread. And they need to be replaced every 6 months.
You are better off spending the $30 to $40 and getting an accurate and reliable refractometer.

what is a good brand of refractometer?

A lot of people use the blue one (not sure what the brand is) from Drs. Foster and Smith. I got mine off of Ebay, it was a no-name knock off brand. Be sure you get calibration fluid with it (it costs $4 or something) so you can make sure it's working.
This is the one on Drs. Foster and Smith. You can find them cheaper on other sites, though.

I got mine off of EBay too. It says ATC on it so maybe that's the brand. Invest in one, they aren't that expensive. Otherwise, with a hydrometer you will be guessing all the time. I got a different reading everyday with my hydrometer even when it was new.
