This is strait from GE's website.
How does GE Silicone II Window and Door with BioSeal save you money and hassle of repairing water damage? By combining silicone’s low shrinkage, maximum UV resistance and perma-flex properties with better adhesion, lower odor, and greater surface compatibility. Silicone II Window and Door is the gold standard in the sealant category.
I have been to their website and read that, but that does not tell me anything about the product. From my websearch I have found that GE silicone II did not always have what they call bioseal, atleast it wasn't on the label. I have also found claims that bioseal is nothing new and it is merely marketing term. If this is true the people who used GE silicone II that did not include the bioseal label were using the same stuff that now is all labeled with bioseal. Of course I have not found any evidence reliable enough to convince me to risk using it with my tank.
On another note, I went looking at walmart for aquarium silicone, they did not have it at my local walmart so I will probably have to try somewhere else. However I did look at the GE silicone I which does not have any claims about mold resistence. I read the fine print on the tube and it says not for use with aquariums. Silicone II also states not for use with aquariums. I would guess that is due to the fact that they 1. haven't tested the products for use with aquariums, 2. the company does not want to deal with the liability in the case it leaks, or 3. they can make more money by selling a seperate type specifically for aquariums.
Just a thought about the bioseal in silicone II. It is too prevent mold growth but it is only designed to prevent mold growth on the silicone itself. If the mold resistence is supposed to last for the lifetime of the silicone the resistence would seem to have to be a property of the silicone itself and not a chemical that slowly gets released.
