Why can't I use this silicone for my tank?

It says 100 per cent silicone rubber, but on the back it says not for aquariums (see picture). What gives? It says it contains Methyltriacetoxysilane? Is that bad?

HELP!

GE silicone I is safe for use in aquariums. GE silicone II is not, it has mold inhibitors.

Just did some research. It turns out even GE silicone labeled 100 % silicone HAS some mold inhibitors!!!

This is what I use, GE1 silicone for windows and doors, no problem.

But i've read they add mold inhibitors to all their lines?

I think I've read that they include the aquarium bit so they aren't liable in the event that the silicone pops and your house is flooded with hundreds of gallons of water.

I used the same stuff it's been a year with no deaths from the tank

About 6 months ago (probably more). I resealed a 150 gallon tank with GE Silicon I. No problems...everyone is happy.

But what about this report that GE puts the mold inhibitors in ALL their lines?

Then, pass on GE. Look for 100% silicone sealant (Aqueon is a good brand). I've never understood why anyone would look for cheap alternatives on something that can save him/her from a home-damaging flood and the loss of expensive specimens. If someone can't afford the safest basic necessities of the hobby they should look for another hobby.
