Funny that you should ask. Currently my bp is in a 10 gallon glass tank, however after one of the stickys I saw on here(the reason I found the forum) I am looking to switch to a Rubbermaid tub of some sort. I happened to check at Wal-Mart earlier and they have a number of different sizes to choose from. The more I read about using these tubs the more I want to make the switch. But I'm still trying to figure out the best, and safest way to heat the warm side? I've read flex/heat tape, UTH, and human heating pads. But it seems like these would be dangerous/hazardous towards starting a fire of some sort? I know I would need a stat for the flex tape at the very least, maybe even the UTH too? But it would be sitting on a wooden surface so that's why I worry. Any suggestions. (also sorry that this sort of got off topic. Haha)
