Cbr (humidity)

[Coojo]

So, i have had a nice 24/7 battle with humidity between me and my CRB's ever so dry tank. SO, as of now.... i have:

Big ol' bowl of water that is wide under the heat lamp.
Two towels that i moisten everyday on top of the screen
I Spray the thing like 3 times+ a day
I have another big *** bowl of damp moss.

As of now... i am keeping it at around 60%. sometimes as low at 50%
If i leave it alone for over two hours... it will go around there. And lets be honest. It's not possible to check every two hours. When i do keep an eye around it... I can get it around 70-80% which i am allot more comfortable with. But still. It's a huge pain in the *** to keep the thing up.

So, i suppose my question IS... What else can i do? And please offer any other suggestions in as great of detail as you can. I mean, i know its in an aquarium. But damn.

Extra info: 50G Tank (Wish it was bigger), It's away from drafty places and it is quite hot alot of the time. Temperature is nothing to worry about.
