Hello, I recently re-scaped one of my aquariums using a new substrate, I wanted black sand specifically, but couldn't find any locally and unipac sand looked grey to me. On further searching I found what seemed to be true black sand listed on ebay - this stuff The day after the re-scape my neocaridina shrimp and ramshorn snails died, the fish however are fine. All the parameters are ok, unfortunately I don't have a test for metals.
I've messaged the seller to try and figure out where this "sand" is obtained and what it consists of, but as of yet I have received no response. I'm hoping that someone on here could help me figure out what this stuff actually is, and what in it could have caused my invertebrates to die off. My only guess is that somewhere along the line the "sand" may have been exposed to copper, or other harmful chemicals in the production process. I am to blame for this, I should not have used an unknown substance in my aquarium. I will not be making this mistake again.
If anyone could clue me in on what this stuff is, and what may have killed my invertebrates, I would be grateful.
