I am currently skimmerless and my chaeto grew a little when I first turned the skimmer off. Now that the Xenia has grown to fill the surplus of nutrients created, the chaeto growth has stalled. Also when I remove it I see no difference in amount of algae in the DT. Now when I do Xenia pruning I see an almost immediate algae bloom on my glass for about a week. Until the growth of the Xenia fills the void.
Troy, your xenia fuge is easily one of the most beautiful things I've ever seen, and also super beneficial. How often do you prune it? I'd imagine it grows like crazy.
