Hello,
I have a 44 gallon freshwater aquarium and have a few Cory catfish in it. I currently have gravel but I know gravel is not good for cory catfish. I wanted to know if I could switch my substrate from gravel to sand and the best way to do this. Also, if I do this is there a way to keep some of the beneficial bacteria that was in the gravel? I have heard that putting some of the gravel in a sock and keeping it in the tank for a while helps but I wanted to hear some opinions on this matter,
Thanks.
