I bought some black Marina gravel at Petsmart last night to add some dept and texture to my substrate, as I've only got pebbles and small rocks there now. When I opened the bag, I noticed it had quite a smell, like mothballs. I rinsed it thoroughly and soaked it overnight in hot water. I rinsed it again this morning, and it still smells. You can smell it a bit when the gravel is covered in water, but I have to put my nose right next to the water. When I grab a handful of gravel up and bring it out of the water and smell it, though... whew! It stinks. Like mothballs, that's the closest thing I can compare it to. Anyone experienced this? Should I return it or does it wear off?
Thanks in advance.
