The tank was not heated. I live in South Florida, indoor temp is always around low to mid 70s in the Summer. The "Winters" (for lack of a better word) never get really cold. In the first post, I advise not to use this method with a heater, unless you are attaching it somewhere else.
I'm not worried about a rescape. The goal when I go to AGA in November, is to pick up some plants for a rescape. I should get on top of ordering some supplies for the rescape.
