GE Silicone Problems..
 
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.

I've been using Adbond 005 100% silicone, its a green tube with the fish on the label. I get mine at Castle Building Center and I think Industrial paints and plastics and Ace hardware also carry it

If you're reading this after the fact, here is some useful info..

. GE didn't even list the petroleum distillates in their MSDS until recently as they were a trade secret.

Is there away to determine what is bad or good by the packaging or some other test? I recently used a small amount of GE#1 but it was from a tube I've had lying around for quite some time. I never saw any effects but would like to check if possible.

I went and bought weather shield silicon which states aquarium safe on the tube. From home hardware for around $7

If the bottle says 100% silicone, it's safe to use.

99.999999......% or less is not safe to use

This is not accurate info. This thread is to list products you've used successfully, and where you bought it.
