I have a propane heater my parents have a central heat and air. Which can possibly give off harmful toxins?
I don't know about polyester resin, but you can get silicon aquarium sealant cheap at Walmart. Use a cheap paint brush to apply a few coats to what ever you want in your tank. It dries clear and seals the object so that it doesn't harm the fish. I've done this for years and have never had a problem. Really. I currently have 4 tanks running. All with home-made, silicone sealed decorations.
Yea! If you are concerned about getting it done may be you shouldn't. My sis works in a tattoo place and she does ALL kinds of piercings. She says that about 25% or 1 in 4 get infected because the person does not follow the cleaning instructions. The Dr. bills can be more expensive than the piercing.
