Keeping a Shrimp Tank Cool During Hot Weather

Reduce heat at the source

Move the aquarium out of direct sun and away from hot equipment. A fan across the water surface can increase evaporative cooling, but it also raises evaporation.

Monitor the tank with a thermometer and keep the lid and airflow balanced. Keep electrical devices clear of splashes.

Avoid emergency swings

Do not put ice directly into the aquarium or pour in cold water. Sudden cooling can stress shrimp and create uneven temperature zones.

If heat persists, use a controlled aquarium cooling plan and maintain oxygenation. Refill evaporation carefully and continue watching the tank after temperatures settle.

For your own tank

Check the thermometer during the warmest part of the day and again overnight. Fans increase evaporation, so monitor water level and top off carefully. Keep lights and pumps ventilated, and avoid emergency cooling methods that create a rapid temperature drop.
