I know that you can use 100% silicone sealant from any hardware store for use in aquariums, but I wasn't sure about one thing. Most of the stuff that we have is labeled 100% silicone, but it also says things like "mold and mildew resistant". Is this safe...I mean, is it just naturally resistant or do they add things? Of course, then it wouldn't be 100% silicone, but who knows?
Thanks for any replies! BTW I'm just looking to see if the stuff that I used on a tank divider (which I haven't used yet of course) is safe to use.
