Yes, but after 6 hours they say to do AT LEAST a 25% water change and add as much carbon as you can. This is the point where I am talking about. Is it necessary to add carbon? Or, is it ok to only do the water change without adding carbon? Maybe do a 30-40% water change only?
.....what Im getting at is, I do not have any carbon. Should I buy some? Custom aquatic has a 9lb. bag for about $30 plus shipping. Should I buy that?
