Last night when the lights went off everything looked good, today my two dominos are covered in white spots and are probably already dead. My tank was set up in November and has had basically no problems. Here are the basics: 65 gal
, live sand and rock, sump type filter, protein skimmer (just added 1 week ago). SG
1.024, ammonia, nitrates, and nitrites are (very) slightly elevated. They were more elevated last week and I did a 20% water change and got things back to normal. As for livestock, 2 dominos, 2 yellow tail damsels, 1 small yellow tang, one fire fish, 2 scollops, 1 brittle star, 1 hermit crab, 1 emerald crab, and a few snails.
What should I do?
