My idea for this water chiller is to have a water pump of some sort connect to airline tubing and pump the water out of the aquarium and through a small cooler full of ice. The tubing will be coiled inside to cooler to maximize cooling time. The now cooler water will then be pumped back into the tank, hopefully cooling it. (The actual tank water will not come into contact with the chlorinated ice cube water, just run through it inside the tubing) I will have to restock the small cooler with ice nightly.
I'll post a drawing when I get home from work and will also post pictures along the way.
I have an empty bucket (or I will find a 10 gal
Rubbermaid) that I will be testing the pump on and monitoring temperatures over the next few days.
This chiller will be for a 10 gallon tank and will only be in place until I save up an extra $200 for a mini chiller.
Any help, thoughts, opinions, advice, and personal experience are very welcome.
