Ok here is the deal, I went to HD that had a couple years ago the south down sand I had used in my tank. well now they did not, but had bags that looks like the same colors and everything. Someone told me before that southdown had several different names and bla bla bla. I did the vinegar test and it fizzed, the only thing confusing me is that on the bag it said not recomended for aquarium use.. is this a prob?
