I have been putting one smallish bag each of GFO and GAC in the return area of the refugium for my 75g mixed reef tank, in the first chamber just below the filter sock. The water flows thru rolled up filter cloth inbetween first and second chamber, and into the second chamber which holds a skimmer and heater.
I just added a couple balls of chaeto into this first chamber, and just today removed the bags of GFO/GAC. My question is: Do I need or benefit from the GFO/GAC, and do I need it with the addition of the chaeto?
Thanks in advance!
