In the video Joey does an awesome job explaining the steps to build this aquarium chiller and it’s super simple to follow along.
He also explains how the chilling process works, here are the key take aways of how this DIY aqurium chiller works;
1) Longer Hose = Cooler Water
The water is pumped into the fridge and circulates through the hoses that you placed in the fridge, then back out to your aquarium. Longer Hose = Cooler Water.
The water gets cooled becuase of the time the water spends in the fridge. Or, the longer the hose the longer water has a chance to cool.


2) Slower Flow = Cooler Water
The flow of the water also impacts how cool the water will get. Slower Flow = Cooler Water.
To control the water flow you can install a ball valve on the output end to help control water flow.
