Aquarium builders should read these Data Sheets, unless I missed it I could not find anywhere where it states that GE-SCS 1200 is aquarium safe. The last point on page .02 under not recommended is a good clue that it shouldn't be used in continuous contact with or under water.

Interesting.

From what I am reading it says "Contact Momentive technical services for applications where sealant is used underwater or in continuous contact with water."

The other widely used silicone for aquarium building is the Momentive RTV-100.

I don't build aquariums but have always used NuFlex 333 Aquarium silicone for resealing jobs and repairs. Recommended by my local glass shop. Think I paid like $10 a tube for it.
