I somehow lost all 4 of these within 3 days of one another. Just did a water test and everything seems fine. All other corals are fine, did a 50 percent water change anyway. All that to say does anyone have any dbtcs?
+1, fix your issues first. What are you testing for? Can you post those numbers? What's your light cycle like? What lights are you using? How old are the bulbs? How is your filtration?
