Saltwater Aquarium 101 - Cooling Fan

Remember I wrote, the alternative for an aquarium chiller is a fan?
The cooling fan, uses the concept of blowing across the water surface to increase the evaporation rate thus decreasing water temperature @ evaporative cooling.

What does evaporation has anything to do with decreasing the water temperature?
Imagine when you want to drink or eat something and its too hot, subconsciously you blow it to cool it down, the same thing. Let's rewind a bit of our Physics knowledge, shall we?
When a liquid evaporates, its molecules convert from the liquid phase to the vapor phase and escape from the surface. Heat drives this process. In order for the molecule to leave the liquid surface and escape as a vapor, it must take heat energy with it. The heat that it takes with it comes from the surface from which it evaporated. Since the molecule is taking heat with it as it’s leaving, this has a cooling effect on the surface left behind. This makes it easy to understand evaporative cooling. - (https://sciencing.com/)
Ours is a hang-on type cooling fan, we connect it to a timer to turn it on for every 15 minutes interval. With this method, it helps to keep the water temperature between 28-29 degree Celsius. However, in doing so, we need to top-up 500ml of backup saltwater everyday.
