I planned to use it to store the additives and fish food and whatever else was in the main fridge my wife did not approve of. Anyway... ...in a few hours it was down to 46 degrees measured with a blue point laser thermometer. Then I got the idea to eliminate the middle man and place the top off container in it instead of the one I use to fill it.
The fish products that you want to keep may work best at 46 degrees and that's great. I'll bet that if you try to depress the temperature of the main tank, your unit will work hard to take the edge off but that may be all that you need and everything will work as planned. I hope so.
Never the less, others might want the glass front look and buy a lower end beverage cooler like I did. I thought that I would jump in with my experience even though you have a much better unit than mine because they might go cheap.
I also bought a glass front Haier unit just like yours EXCEPT it was a dorm sized, black finish, lower end fridge. I got it only to store my phytoplankton paste, liquefied sea food and other coral foods, served up with dosing pumps. I didn't think about the fact that a beverage cooler is designed to only go down into the 40's or 50's. I had wanted it to go down to 34 or so.
I looked at the compressor and found that it was the same rating as a fridge of similar size so I call a part replacement company support line to get a refrigerator thermostat instead of the beverage version.
I was so disappointed because the tech wouldn't listen to my smart idea. He started telling me about some piece of plastic tubing. I told him that I found the place where the thermostat wire went through the fridge wall and I could fashion my own gasket. I just knew that I could retrofit the unit and he just wasn't listening to me.
Finally, I decided to listen to him more closely and understood what he was saying. He wanted me to simply put a piece of small ID foam insulation tubing over the probe. That way, when the cooler's real inside temp is 48, the thermostat will think that it is 62 so it will try to drive the cooler temp down. It may drive the temp down to "¦say 29 degrees. Then, you cut some tubing off, a little at a time until you can get the real temperature into a range where the thermostat will allow you to tune the temp to where you want it using the dial. Hmmmm Sometimes, I guess that it pays to listen. Sometimes
