Lowering Temperature in Small Tank

[gdupont]

I have a 5.5 gallon tank and have a few orchids in there that would prefer lower temperatures. Right now the temperature is in the mid 70s, but I would like it in the 60s. How might I go about accomplishing this? I'm using LED lights.

Lower the temperature of the room. Maybe place the tank in front of Air Conditioner. Also add airflow between the lights and the tank (possibly with the AC too).

You can either blow cold air onto it, or set a baking pan filled with ice on top. You can find instruction online to build a heat exchanger to attach to the glass outside, but I recall thinking it was a lot of do it yourself electrical work for not much result.

Does anyone know of a way to attach a cooling unit from a small fridge to a terrarium? Of Course that is entirely too much work for a small terrarium (not worth it unless you have a larger setup), but just thinking outloud.

I'm in a college dorm so no a/c :/ I'll try ice! Thanks.

Maybe you can get a Peltier module? Check out this video.

The Peltier module is what I referred to earlier. It might work for the drop 70F to 60 F, a drop of just over 5C.

Easier to replace/modify the door on the fridge so you can see in than to gut out the components and reinstall on a tank.

I just hate the look of a fridge though.

freeze some water bottles, and put them into the tank at night to lower the temps. It would be even more effective if you have a small PC fan for air flow in the tank.
