[Aquattro]

PSA: There have been several threads recently detailing crashes and issues with tanks after using GE I or II silicone to repair or build new additions to tanks. While GE I has historically been reef safe, and I've used it myself for years, there are reports that they are now adding a mildew inhibitor to this mix as well. This seems to be verified by the crashes reported.
GE 1200 is still highly recommended, as are several other products on the market at hardware stores, marked as "aquarium safe".

Please do a search here for threads detailing the problems and alternate products to use instead.
Alternatively, if anyone wants to post in this thread what they used and where they purchased it, that might make it easier.
Please, no discussions of issues with silicone, just what you used and where you got it.

Thanks.
