Having owned a tank with black silicone I really wish they were all made with it. Much cleaner looking and you cant see the algae that likes to grow on the seam.Why do you want black instead of clear?
Should be. Looking at the ingredients it's all silanes and oil, then a little carbon black for the black. The big thing you want to avoid is fungicides, which I don't see.

It should be fine. You can look at the Questions at Amazon and read the responses also: http://www.amazon.com/08642-Corning-Silicone-Sealant-10-1-Ounce/dp/B0002YOVFODo u recommend DAP, or better yet see anything wrong with DAP?
