Since you are clearly a masochist, you will enjoy every bit of frustration ahead of you. I guess you could see if your light will heat your water. For water movement, maybe just an airline? That might help oxygenate the water. Any then daily water changes? It will be interesting to see how this turns out.

I thought about lighting, I plan on running LEDs, so not a lot of heat. Plus I am trying to avoid a huge temperature change at night.

I do plan on keeping the lid shut tight for most of the day, to minimize the evaporative losses. Opening the lid for an hour a day for gas exchange.

I was thinking I can kill two birds with one stone, by placing the mason jar on a heated turntable. Now will that create enough circulation? Allow for enough gas exchange? etc.

This will be an interesting experiment here in Alberta during the winter.

You might be able to put the jar on one of the mini heaters from hydor...they sell at J&L
