carbon bad = most times not(notice i said most lol )
carbon good= sure it is its a fact
carbon needed to run reeftank = no
carbon need to run a reeftank longterm = whos to know for sure??
if i have a tank for one year maybe i got lucky and had a good year with no carbon while if i have the same tank for ten years maybe i didnt get so lucky and had a few incidents where i was glad i ran carbon, one method compared to the other can ony really be done by a tank to tank basis, your tank in ten years may not be in the same state mine is in ten years and vice versa.
