The IceProbe is the ideal cooling solution for small aquariums. This quiet, reliable, and efficient chiller uses advanced thermoelectric technology to directly covert electricity into cooling power.
With its threaded probe, nylon nut, and silicon washer, the IceProbe, can be easily bulkheaded through a 1.25" hole into siphon overflows, prefilters, sumps, or even directly into acrylic aquariums.
A single IceProbe can cool 10 gallons of water 6-8F below ambient air temperature in a standard aquarium. Multiple IceProbes can be used in a single aquarium to achieve higher temperature differentials.
The IceProbe provides continuous chilling power. A separate temperature controller must be used to turn the the device on or off at predetermined temperatures.
Weighing in at only 2 pounds, the IceProbe® is powered by a separate 12 volt D.C. power supply and draws less than 50 watts.
CoolWorks Aquarium Supplies CoolWorks IceProbe-powered chillers are the most effective way to cool small volumes of liquid. CoolWorks has been providing consumers and business with innovative water cooling proudcts for more than 10 years. The company was founded in 1994 and is dedicated to developing, manufacturing and marketing innovative thermoelectric products. The company was awarded a U.S. patent for their flagship product, the IceProbe, in 1996. The IceProbe was designed as an alternative to compressor-based cooling technology for small scale water chilling. While initially used for cold water dispensing systems, the IceProbe has proven very effective for cooling small aquarium systems.

I have 4 CoolWorks ice probes. Axolots need cold water, below 20oC and are housed in two different 10 gallon tanks. The other two are in two 20 gallon tanks set up for goldfish, which also like cold water. We set up a stainless steel triangle that sits in the corner. This works fairly well, but we ...Read More

I purchased this to resolve issues with heating with Metal Halides on a small tank, however, I received it over a month ago and have yet to be able to use it because it's not designed to sit or attach to anything other than a bulkhead. The cooler if very effective, it just can't be connected without doing some sort of mod if you don't have a bulkhead ready. Also, If you plan on doing a mod to a hang on filter, pay attention to the placement so that the probe doesn't interfere with the filter cartridges. I was very annoyed to find out the probe would only fit into my filter where the cartridge went - either no more HOB filter or don't install it.Hide
