This grease really is the Cats A%! in my opinion. It is non toxic, certified by the NSF for incidental food contact and is completely non water soluble so it doesn't leach (sp?) into your aquarium water at all. It just stays put and keeps things lubricated and sealed. Completely safe for aquarium use in my opinion and 2 years of experience using it has produced zero problems.
1 Tube will last you a lifetime. Ithink I paid something like $7 for it from my local hardware store in Ontario, Canada.
