In theory, GFO can absorb all of phosphate in your tank eventually (if you change your GFO frequently). At the same time, the bacterial triggered by carbon dosing also needs both nitrate and phosphate with some ratio (some say 16:1, but I think different strains of bacterial take those 2 in different ratio. Anyhow they always take more NO3 than PO4). If you tank is running out of PO4, carbon dosing won't do you any good.

Lol. I have no shortage of phosphates
I ask as I stupidly overfed my tank. My wife was feeding while I was at work and I was feeding in evening. Not knowing that she was doing so. Or that she was doing so twice a day. I was feeding in evening. Since I have a shy Cbb which doesn't care for Mh lights so I fed when just t5 were on. I first notice when I spotted HA. and had a stag loose a little flesh. Then with a spike in po4 I changed gfo and decided to try carbon dosing. I also have a refuge with mangroves and Cheto. Though Cheto doesnt want to grow
