I have a 72 gallon tank and my plants aren't doing that well. Somebody suggest trying First Layer.
Yesterday I did a partial water change and added First Layer to the gravel. When I went to bed everybody looked fine. When I woke up this morning I had two dead Bala Sharks and a dead cory cat. I've had all three of those fish for 10+ years and I'm very upset.
Does anybody know what went wrong or have any suggestions to make sure the rest of my fish stay healthy?
