Thanks I google Codium sp an yea thats it .. Thanks ... The Red Slime is my next step I tried light cut back and 2-3 day feeding helped a bit since that pic was taken, but might try something like boyd chemi-clean ... Its a BioCube 14. I don't have that issue in my Larger 30gal tank but i have a protein skimmer and UV on that tank.
