Help Needed: Black Petco Gravel
I have a 46 gallon tank with two inches of white/brown gravel that I don't like the look of, so I bought two 25 pound bags of black Petco brand gravel. My plan is to remove a small amount of white gravel and put the black gravel on top of the existing gravel. I opened one and washed it with a hose then left it in the sun for a few hours to dry. As I was about to start putting the gravel in the tank, I noticed that it had an odd odor and that some of it had small white streaks, so I didn't put it in the tank. I opened several pieces, and found that the insides were white and the coloring was artificial. I'm a bit concerned about putting this in my tank, as the tank is several years old and has cardinal tetras, livebearers, marbled hatchets, and lone red cherry shrimp. Also, I wish to introduce some Amano shrimp in the future. I assume that putting the gravel out in the sun messed up the coloring a bit. Is it risky to put the gravel in? I really don't want to take any risks. If it is indeed toxic, are there any other inert black gravels I can use?
Thanks in advance.
