aquarium safe coating

[Stroker]

I want to paint or coat something so it is safe for fish.

Some people use Krylon in their tanks...

I've heard good things about using Krylon from "pros" on Youtube. I believe the key to it being fish safe is let whatever you paint dry completely before putting it in the tank, like at least 24 hours.

That being said, I did find this letter from Krylon, addressing the issue of using their paint in aquariums. Probably just something to cover their *** since this isn't something they test for. Others swear by the stuff and have had no problems, if cured properly.

Hello Xxxxx,

Thank you for contacting Krylon.

Additionally, we have nothing that is FDA approved, which is important in terms of ingestion. Our products may harm the aquarium life.
