It is at the end of the cycling my 24g. I am rdy to add fish and coral to the tank. AS i know the bio-ball and the cermial will creat nitrate problem in the future. SO i take it all out and planning to put carbon in there. I bought the KENT Marine Reef Carbon and put 2-4 teaspoon to a filter bag. Question is while i reading the lable on the container it say i should only left the carbon not more than 3days becasue it will adsort all the trace minerals and organics stuff. Is it true ?? how long u guy left your carbon bag inside ? how offer you guy change it ? Thank for the input. :happyfish
