When you buy glass aquarium lids, there's a plastic strip that's about 2" wide that goes along the back. This strip is made so you can cut it out to make way for overflows and other things. the problem is that once it's cut, you can't change it when you change equipment. Is there anywhere that sells these plastic strips without having to buy the entire glass top?
If I can't find them locally, I am willing to buy online, so if you know an online source please post it up.
