This may sound like a silly question, but I just thought I'd check before using it on my livestock. I was at the fish store the other day and decided to get the large bottle of Laguna Pond Conditioner instead of the usual Hagen. My reasoning was that it conditions twice as much water for the same price and with large 130gallon water changes 3-4 times a week I was tearing through the other stuff. In an effort to hopefully save money I went with the stuff made for ponds. I just wanted to make sure this was safe to use in my aquarium (my gut says yes, but just wanted to check) and also is anyone uses it on here. Thanks in advance.
