Gfo and carbon dosing

[Proteus]

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
