From 10 gal to 30 gal??????

Here is the BP caresheet. It will tell you everything you need to know.

Per the caresheet, the UTH temperature needs to be in the range of 88-94. I keep mine on 91.

Those tunnel logs can be a pain when it comes to getting the snake out. Ideally, you'd want something you can lift off of the snake, not something where you'll have to reach your hand in to get it.

I've never heard of a cork log, so I don't know if you can bake those.
