Jonny to the rescue! hahaha

Alan is it possible your algae in your refugium went asextual. I have never seen this phenomonom(never spelt this word) happen so when i saw your tank a few days ago i couldnt tell you what it was, this is my suggestion though.

For the first 8 months of my tanks existance i ran carbon 24/7 and when i did water changes my water that was taken out in the bucket was still green.
since adding my sump i have not used carbon, so about a month now and i definatley notice a little more green tinge to the water.

Maybe running the carbon will clean it up.

Oh on another note how's the leather's doing?
