JBJ Arctica 1/2 hp chiller

[elviraveloz]

I bought an established 175 gallons Bowfront aquarium with a chiller included is a JBJ Arctica 1/2HP titanium 115 volt. We just disconnected all the tubings went home opened it and clean inside with an air pressure machine I have and connected again. I performed a 75% water change and the water temperature drop to 71 yesterday morning. This morning the temperature is only 75. Why is taking so long to reach 79.

What's the air temperature, and what temp did you set the chiller's controller to?

[elviraveloz]

Air temperature is 73. I set up temperature on chiller 79. Right now still 75

Chiller's don't heat the water You need a heater for that. The chiller is to prevent the water from getting too hot.

Thank you for your information I thought some chillers will do both.

There are some chillers out there that have also have a built in heater and utilize a dual stage controller to allow for both heating and chilling. There are also some heat pumps out there that will do both, those these are usually rather expensive and typically only seen in aquaculture settings. The one you have is the typical, strictly a chiller. Since it utilizes a built in single stage controller, the controller only will operate the chiller for chilling. To prevent having a chiller and heater's fighting, without use of dual stage controller, set your chiller for a couple of degrees higher than your heater.
