Is is okay to add cylcing bacteria (e.g. Cylce or Bio-Spira) which the goldfish already in the tank?
If no, should I just keep up with the water changes and let the fish ride it out or are there other options? I thought the tank would have cycled more more quickly by using the water and filter media from an exiting cycled tank, but I was wrong and the ammonia is running high and the water is cloudy.
Yesterday I did a 30% water change and added some "live gravel' from an exisiting tank. The fish seem to be doing fine, eating, swimming and pooping, but I'm worried.
Any suggestions?
