I have a 40 gallon tank with a solid screen top. The top is very tight fitting and very hard to get off to get to my geckos. I want to install two doors into the top but i'm unsure of what materials to use and how to go about it. Any suggestions? I think once i find and make the door and frame for it, the instilation will be easy as i can either use silicone or spot weld (if the door material is metal).
Any help is greatly appreciated
