It looks like I am probably going to be moving in a few weeks. The place I am moving into is much drier (if that is even possible!) than my current house. The heating system just fries every last drop of moisture out of the air. I need to come up with a way to seal Shiiva's tank to keep the humidity in better (heat isn't a problem). She is in a 40 breeder and the lid that I have is a metal screen that folds in half to open. (Held down by cage clips). I need something that is thin so I can still open the cage all of the way, that will be ruined by water exposure (I can seal if needed), a material that is relatively easy to work with (I only have basic construction tools - jig saw, drill, sander), and ideally something that will not catch on fire or melt near the heat lamps. I have a few ideas of my own, but I was hoping perhaps someone here might have some better suggestions. My plan is to cover about 3/4 of the screen. The other 1/4 will be open for the heat lights (Right now she has a light and a CHE). In the covered portion I would like to cut a small hole to allow a hose to be secured for the humidifier. I have a fogger, but it broke quickly and I feel certain that if I buy a new one that will break too. What I am hoping to do is to modify my humidifier to attach it to a hose that can feed into her tank via the hose attached to the screen lid. I also do not intend to cut big holes in the screen itself, and any drilling into the screen should be kept to a minimum (though I sexpect some will be necessary to secure it). I don't want to mess the lid up or have the potential for wire edges that Shiiva might cut herself on. I do have some spare plexi glass scraps, but that is so easy to scratch and crack. I can also paint and varnish wood if that is the best option, I just worry about it getting too close to the heat lamps (esp when I open the cage and keep it open for a little bit to clean it). Money is not a big issue right now, but I don't want something drastically expensive of course. I would even be willing to pay someone to make it, but shipping would be an arm and a leg.
