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 water is required
- Do not add unmixed synthetic salt to an aquarium containing live stock
- Consult your aqua one retailer for further information
