How to Keep your Aquarium Cool

Tips to keep your aquarium cool during hot weather

During hot weather, your aquarium water temperature will inevitably increase.

Generally, if this is not sudden or prolonged, it is not a problem, but higher temperatures will mean less dissolved oxygen and can leave your fish gasping for air.

Here are a few actions you can take to minimise any impact:

- Reduce ambient light in the room

- Reduce aquarium lighting (intensity and period)

- Increase surface agitation of the water

- Feed smaller portions of food

- Consider small (10-20%) water changes

Do Not switch off the thermostatically controlled aquarium heater

Do Not add cold water or ice directly to the aquarium
