sealing a beer can for display in SW aquarium

**glarior** · 11-02-2012, 08:05 PM

I am doing a big fish tank build and my father is helping me with the manual labor part of it. I want to surprise him and add a beer can (or cans) to the tank when completed since I am paying him in beer lol.

What would I use that will seal the can and not harm anything in the tank?

Why seal it? It needs to sink. But you don't want fish trying to get inside the can as that's some sharp metal.

you should definately use a barely cracked then sealed can for a few reasons. first because you need the air to get out but you dont want the fish to try and get in.. and second, because you dont wanna have to coat the inside of the can with protective sealant..

not really sure of the type of sealent/paint you need to get. ill try and help you look.

He is refering to sealing it to prevent metals from entering the water hobbs. Not closing the can.

Krylon fusion might be a option if you can find it uncolored

I can ground the lid if I had to.

Yea, thats what I was thinking so it will sink. I just don't know the kind of sealant. They talk about it all the time on TV but no clue what it really is. If you find something let me know.

I will keep looking as well

Thanks!
