Is this silicone ok for my tank. Pic included

  • We are currently upgrading MFK. thanks! -neo
It took me a few minutes but I found this in an old thread.

"I was told not to use the GE silicone II because it had mold protection stuff in it, the chemicals for the mold protection will not allow algae to grow, and it will be harmful to the fish, hopefully with a tank that large it will dilute all the chemicals."

There is a sticky at the top of the DIY section on Silicones that you might want to take a look at.
 
Evidently GE Silicone II has anti-bacterial/mildew called Bio-Guard.

This may leach into the tank and/or kill nitrifying bacteria.

I would look for anything which is considered "Food Safe" or GE Silicone I, which evidently works!
