Has anyone used GE II window/door/attic/basement in there vivarium before? I just bought it becuase it was the only silicone that came in brown. It mentions nothin about bio-seal or being aquarium safe or even being toxic. The only thing it mentions is that it provides a mold free product protection, which scares me. I know that people have said that they use ge silicone 2 with bio seal before which is the mold prohibitor and many have used it before they put the bioseal label on it even tho it was still in there. Think its safe? Or should i return it?
