Then you are doomed to a life of second-rate fishkeeping and will never join the ranks of the elite refractometer club (�10 subscription fee but you do get a T-shirt) You can get one at your LFS tomorrow.

Go for the ones with the ATC feature.
Hydrometers are about as accurate as my grandma with a shotgun at 500m.
