GE Silicone I

[Tarolisol]

Are you refering to the silicon at homedepot doors and windows if you are i wouldnt use it i was going to and then buk a neer said even though i says 100% silicon it could still contain anti fungus stuff or somthing along those lines. So this being said i called GE a few days latter and they said it does contain some sort of stuff like that i cant remember what they called it and said to use construction silicon GE1200 and one other kind for my aquarium.
