Thank you!! I didn't realize that about the thermostat - what temp should I set it to since it will lose some heat after traveling through the glass and substrate? Also, its a very snug fit between the table and the tank so the probe will be snug too, does that pose a problem? I've heard there should be some air flow down there but there really isn't any (the inner grooves of the tank fit into the top of the table perfectly).

I forgot to mention in the post but I have lots more branches and plants on the way to make it more secure - so no worries there
