Silicone??
 

is 100% pure silicone ok to use in a sump?? Dumb Question?..you tell me. :rolleyes:

You should be fine. I know the GE 1200 (can anyone confirm?) is okay to use. On the back it should say Ideal for aquarium repair. You can get it at Canadian Tire for around 6$.

thanks bud...

Just don't use the GE Silicone II. It is not suitable for aquariums or submersion in water. DAMHIKT (but at least I discovered the mistake before it turned to disaster)

If you cant find the ge1200 stuff than the type I is fine to use. As it was mentioned just don't use II.

Home Hardware has their own brand that aquarium safe.

like Wendell said, homehardware has their own and its usually pretty cheap when you get it in a 3pack
