My grape Caulapera crashed for a second time in my refugium. I woke up to a clouded tank. I ran some carbon, removed the Caulapera, and performed a water change. (Nothing else was affected.) I do most of the items I have read about to prevent this but this is the second time. I run lights 24/7, prune regularly, and dose iron. It grows like crazy and I believe it helped eliminate my hair algae. I would now like to try some chaetomorpha. I am having trouble finding this algae. Does anyone have some suggestions on where to find chaetomorpha? (All I have seen in searches is people trading it.) Thanks.
