i bought some polished river rocks from craft store. was going to put some in my tank just now & i read tag it said not to use in aquariums. can i use them? i thought i read on here that different people have used things from craft stores with no ill effect.
What he said. Many things can go either way, but when something specifically says not for aquarium use, it's usually for a reason. Many coatings that make things look polished or shiny do not hold up in water, dissolve and can pollute the water.
