My roommate is allergic to nearly every type of appropriate substrate, so I decided, at the advice of the reptile department manager at a local pet store, to try Care Fresh, which is like compressed, shredded, recycled newspaper used most frequently in rabbit enclosures. Have any of you used this before? What have your experiences been? I added sphagnum moss on top in one corner to help with humidity.

Also, the UTH I have isn't keeping the tank warm enough, so I'm going out to get a heat bulb today. I have a 5 1/2" clamp lamp, and the tank is 29 gallons. What wattage is appropriate? Can I get a red bulb? Can I leave that on all night if I do? Will a CHE get too hot?

Thanks!
