I have heard of some having it go a bit yellow but I've personally never had that happen. Get it a HomeHardware for $9 for a 3 tube contractor pack.

Thanks! I'll check it out. Seems like an awesome deal for 3 bucks a tube!

I've also found something at Industrial plastics that is Aquarium safe.. Let's see what that is all about!
