WARNING: GE Silicone I and II probably no longer safe due to added mildew inhibitor

If this is true then the only thing I can think would be safe would be aquarium silicon, which sucks cause it come in a small toothpaste style tube and is much more expensive

Looks like its going to be Titebond III and Gorilla Glue for backgrounds

It comes in standard tubes as well. At Home Hardware (a Canadian chain, sorry) their standard house brand silicone is labeled as aquarium safe and is something like $10 for 3 300mL tubes. I've been using it with no problems for a few years. It only comes in clear or white though.

BioSeal has been in GE Silicone for years, there are threads dating back to 2006 talking about it being added, along with debates over whether or not it poses any danger. From most of what I've read, it's always been in there, they just never labeled it as such. I use CRL black silicone, just because it's what our local fish tank maker uses and I can purchase it by the case. I used GE before and haven't noticed any problems with my frogs or plants perishing though.

Just a warning for anyone wanting to use the CRL, the smell is rather intense and it's best done outdoors. I used it indoors, like I did with the GE, and I swear my lungs were on fire and I was coughing for the next 20 minutes.

i use any kind that is simply 100% silicone. If you aren't sure what product sa re 100% silicone, contact the company that makes it.

I don't know how they get away with it, but even stuff that claims to be 100% silicone can contain mildew inhibitor.

For proof, here's a pic I copied off of Canreef...

Yeah I did indoors in a small apartment and drove my wife insane. I find that the black silicon to be more potent than the clear though.
