Well, I'm stumped. After looking at my tank again (normally I'm focused entirely on "Phil", to a degree that I'm practically oblivious to everything else) I realized that the cnidarian devils are in there on the rocks in the typical huge numbers- 2+ per square inch of rock surface. The reason I'm stumped is that a lot are from before phil went in the tank (rocks are from 90g tanks refugium), and a week before I got him, I went on kalk-injecting spree. The whole week the tank looked like it was having an underwater version of a blizzard! (I did a major water change before he went in to fix the calcium and pH levels, which were a bit off from the dosings) One would think that would have finished them-worked in the 90 and that was with tank feedings and the extra kalk was blown away from the powerheads. Anyhoo, any ideas how to get rid of them?
