I'm thinking of adding carbon to my tank to absorb my tannins from driftwood along with improving my water clarity.
I have a 210 gallon with a 55 gallon sump... Been up and running for 3 months. My reading are at zero for the main three for the last month.
I do 30% water changes every 4 days.
So my question is...... Do I just add carbon granules to a filter bag and toss it into the water in my sump? or do I throw into into the area where the bioballs are? Does it matter?
Here is a picture of my sump.
