I am getting ready to run activated carbon. I have never used this before, and im wondering since i have a full blown reef tank with the Cuttles and Octos, will the carbon suck out and deplete my additives and essential elements i add for the corals? Calcium is on of my biggest concerns, as i couldnt find much on that at all. I just dont want it to deplete it enough to where im adding stuff all the time. I have been adding in moderation, and everything seems great up till my down spell recently, but things are back to normal and im awaiting some eggs. I keep reading it makes the water clearer.. the thing is i already have crystal water, i was wondering what are the true benifits to running the carbon filtration? Besides helping with a inking incident.
