Silicon Help Please!

The Trans Am Kid

What kind of Silicon is safe. I wanna do the cave project and I bought some 100% Silicon, but then I read I need to buy non-toxic. Is this right? Please help me out. A picture of the silicon bottle would be a great help. Thanks a lot!

The only safe siliocne I know of is the stuff that is 100% silicone, usually the only ingredient it 100% VOC. I think that GE silicone I is one of the safe ones.

You need to buy aquarium safe silicone. I work at a glass company and we have had requests to build aquariums for customers and you definitely need the aquarium safe stuff. We sell it at our store and its 6.95 a tube. But you need a caulking gun. I haven't seen it come in anything but a large tube. Might want to check your local hardware store or even some place like home depot sould have it.

As Fish_4_All said GE Silicone I Door & Window

It will NOT have the Bio-Seal label on it.

It's the easiest to find (HD, Lowes, Aces etc.).

Wal-Msrt sells one. It is in a squeeze tube: LocTite clear silicon. It states on the package that it is aquarium safe, but must cure 48 hours. I have used this to make a sort of rock mountain for my biorb and it works great dries clear and and hasn't harmed a fish at all.

I looked at this one and I am pretty sure this said not for aquarium use BUT that may only mean it will not hold well enough to BUILD an aquarium. I think lots of people use this safely for decorations.

Whichever GE silicone is 100% VOC is perfect for building fish tanks. I know many members on here and elsehwere that have used it will many years of leakfree safe DIY aquariums. Is what I will be using to build my custom tank when i have room to set it up.
