Aqua Source Floating Pond Thermometer

Aqua Source Floating Pond Thermometer

This simple floating thermometer makes it easy to check pond-water temperature before feeding koi or making seasonal changes to pond care. It shows both Celsius and Fahrenheit and includes an anchor line so it can be kept in a consistent, accessible part of the pond.

Fish metabolism changes with water temperature. A reliable reading is especially useful during autumn, winter and spring, when a sunny afternoon can make the air feel warmer while the pond remains cold. Check the water rather than relying on the weather forecast.

Key features

• Floats on the pond surface
• Easy-to-read Celsius and Fahrenheit scales
• Anchor line included
• Suitable for koi ponds, wildlife ponds and ornamental water features
• No batteries required

How to use it

1. Secure the anchor line to a suitable point at the pond edge.
2. Place the thermometer where it can float freely, away from a heater outlet or other localised heat source.
3. Allow time for the thermometer to settle to the water temperature before reading it.
4. Use the result alongside the temperature guidance for your exact fish food, treatment or maintenance task.

Our practical view: Keep the thermometer in the same representative area of the pond and check it at a similar time each day. That makes the trend much more useful than occasional readings taken in different locations.
