Thank you all for your great replies.
Yes-I have a glass tank. RHP seem great, but they are a bit too pricey for me. I like the idea of the garden wire, however i'm a bit nervous of the wire also heating up. I am using a 150W CHE currently. I also like the idea of the second UTH, but I'd be concerned about the humidity. I may use the hook idea, only issue is that I'll have no idea how long ill need it to be to reach over the top of tank.
