Ok so I have been battling this junk for about half a year now.. At one point I took everything out and to clean and now it's making it's appearance again.. It grows very long and attaches at a dense point to almost anything. Any idea what it is? (I think its beard algae) and how do I kill it???
+1 on Staghorn. If you use pressurized CO2 try increasing it. Increasing the flow rate may help. It is also caused by too much organics so a deep clean of everything will may help as well.
I had a huge staghorn problem. I kept the tank immaculate, my flow was actually too strong and my CO2 drop checker was always yellow. Excel seemed totally ineffective as well as peroxide spot treatments. I finally followed the suggestion above. It was all killed, happy days. Well as expected it came back. I finally quit using DYI CO2. Guess whats gone now. The staghorn and BBA. I won't be using DYI CO2 ever again. I think it causes more problems than it corrects. Just my own experiences.
