I had a "bobbing" thermometer/hydrometer thingy 15 years ago. NOT really any good IMO. I bought a refractometer on the auction site. $34 plus shipping, LOVE IT! If yours has a thermometer in it, do not leave it in the tank. The flow could make it bump into something and crack. Mercury and glass shards are not what ya want in the tank IMO. Ha!
