silicone, again

[fishymike]

would this silicone be good for aquariums?

GE ll 100% silicone. Light gray concrete and masonry silicone sealant.

I wouldn't use it, no. The colored stuff contains something other than silicone (dyes) and I think something else as well to make it work on masonry.

Dap makes 100% silicone that even states it is safe for aquariums.

your supposed to use silicone 1 because it dosnt have the anti mildew and stuff but i can never find it. the walmart aquarium sealant isnt too expensive and it works fine.

Since we are on the topic, I was wondering something. I am planning on building a slate cave for a tank and was thinking I could save some money and go to Home Depot for the silicone. Will they have the right stuff for me? Would it be cheaper than the All-glass aquarium stuff they have at Big Al's? I will be going to both stores tomorrow but Big Al's will be first so I would like to know before going. Thanks guys.

Yes Capt'n, they'll have it. Make sure it's 100% Silicone without mold and mildew inhibitors, added dyes, etc....

[Karlsbad]

Isn't there something called aquarium sealant that's available all over the place?

[beviking]

Yup. It's re-packaged 100% silicone w/o mold and mildew inhibitors, added dyes, etc... that costs more.:)

Home Depot and most hardware stores will carry the silicone. It does take a little reading to get "just silcone" but worth it. For building a slate cave or any heavy rock work I would suggest epoxy instead of silicon. The silicone tends to loose its bonds with rock surfaces when submerged over time. Many epoxy cure inert and should be non-toxic then.

They do sell a CLEAR GE Silicone II (for doors and windows) that comes in non mildew formula. Wouldn't this work?

[JesseJ]

It schould. The stuff I used was Rona Door & Window 2 sealant. It says that it is safe for aquariums on it.
