Hagen Living Sea Hydrometer-Thermometer C and F, Large, 12-Inch

Pro's:

This hydrometer is more accurate than it's smaller counterparts.

Con's:

The extra size and weight make it a little more likely to break, I have purchased and broken this hydrometer before. These break easily in the center when picked up from one end instead of the middle. The tip also can shatter if it is dropped into the water and hits the bottom or a hard surface.

My impression after owning several glass hydrometers of various sizes:

For aquarium use just buy the smaller hydrometers such as: Living Sea Hydrometer, Celsius & Fahrenheit, Small, 8 Inches, they work just as well when precise accuracy isn't necessary and they tend to last longer.

Even though this shows up under the search terms 'brewing hydrometer' it is a SALINE hydrometer. It will NOT measure specific gravity of wort for home brewing.
