I've had enough of these dinos and nothing I do seems to work long term (rasing nutrients, multiple 3 day blackouts, running only blue lights, siphoning sand daily, blowing off rocks, UVs plumbed to and from display, adding pods, dosing microbacter, Dr. Tim's recipe for dinos, dosing silica, and most recently the rasing temp method). At this point, I'm willing to try something a little more drastic. For those of you who have used dino x, what has your experience? Did it get rid of the dinos for good? Did you suffer any livestock loss as a result of it? I know sea urchins and clams can be sensitive to it so I've already moved my urchins to another tank. As far as SPS, I just have a few acro frags and some Monti caps.
