Silicone II update (bad news)

[BadFishPa]

I just used Red Devil, Black Multi Pupose formula 100% Silicon for my winter holding tank for my Goldfish. I let it dry 4 days and wiped off the area with a wet rag a few times after it cured and had no problems. No carbon or heat just a sponge filter and some powerheads..

I used DAP brand black silicone window & door for my cork on slate project, haven't ever noticed problems from it. I had to have my True Value hardware order it for me. No mildewcides

I've always heard that one suggested as safe. I did notice though that the DAP window/door at Lowes now has a mold/mildew protection label on it. Not sure if it is as bad as the GE stuff is said to be, but something for people to look out for now.

I have used GE II on at least three tanks with no issues. That said I did let the silicone cure for a week dry each time and then water tested for 2 weeks to make sure they would hold up. I think it just needs a longer cure time before adding stock.

Why GE doesn't label the mildewcides and fungicides in GE II is anyone's guess - I sure would want an explanation, myself. I suppose because they don't realize that people are wanting black silicone for aquarium applications?

It is labeled.
It says not for aquarium use.

Black aquarium silicone is not difficult to find on line. Is a couple of dollars more for the proper material not worth it?

10.X ounce tubes of black silicone.
