SM originally told me that Xenia probably wouldn't make it as N and P dropped out. In over a year of running a T5HO scrubber I can verify this is definitely not the case. They grow like wildfire. I try the best I can anymore to keep them at bay but they refuse to die. That and Anthelia / Waving hand grow uncontrollably for me.
I have had some difficulty keeping some LPS corals like Frogspawn and Branching Hammer. They tend to open up a little after cleaning the screen, then close up tightly toward the end of the cleaning period. Still trying to get a handle on this one. Also for some reason ORA Green Birdsnest took a beating (also due to a dino outbreak). Other SPS, like Red Cap, Green/orange Digitata, Tri-color Valida, just love it. Softies no problem, cabbage leather, toadstool mushroom, Colt, love it. Mushrooms love it. I have some fuzzy mushrooms that got 6" in diameter then in just one day they split in 4. One of the clowns hosts in them they're so dense.
