Aqua One Glass Hydrometer

Aqua One Hydrometer with Thermometer Glass provides an accurate reading of temperature and specific gravity.

Green indicators show a safe range of saltwater level and temperature for most saltwater species.

Directions for use:

• Place the hydrometer at the opposite end of the aquarium to the heater (if installed)

• If the green indicator is below the water level more fresh wateer is required

• Do not add unmixed synthetic salt to an aquarium containing live stock

• Consult your aqua one retailer for further information
