i went to my lfs a couple of days ago and i wanted to buy a hydrometer. i started to go to the checkout line when an employee stopped me and said you dont want to buy that one (about $13) you need this one (about $4) so i said ok and bought it. it really sucks. i cant tell how to check the salinity. it looks like a in water thermometer but has a skinnier part at the top for the hydrometer. the brand is aquatic gardens. should i have bought the one that was expensive? or can somebody tell me how to read it?
