Marina Stainless Steel Thermometer

The Marina Stainless Steel Thermometer gives you an accurate, at-a-glance temperature reading from a precision glass thermometer set in a durable stainless steel housing. It hooks over the rim of the aquarium, and a color-coded safety zone shows at a glance whether your water sits in the comfortable range for tropical fish. It is designed for freshwater aquariums. Pair it with a reliable aquarium heater to hold your water in the right range.

• Color-coded safety zone indicator for tropical fish

How to Use

Hook the thermometer over the top rim of the aquarium where you can see it easily, ideally away from the heater so you read the true tank temperature rather than the warm water right at the element. Give it a minute to settle, then check the reading against the printed safety zone.

FAQ

Is this for freshwater or saltwater?
It is designed for freshwater aquariums. Stainless steel is not ideal for long-term use in saltwater, so choose a digital or suction-cup style for a marine tank.

Where should I place it?
Hook it over the top rim, away from the heater, so you read the average tank temperature and not just the warm water near the element.

Fahrenheit or Celsius?
Both. The scale is printed in both units, with a color-coded safety zone for tropical fish.
