I was away for a week and my leather corals are developing these brown spots. It's early, so they are closed but all looks well, tho nitrates are high. Opinions?https://uploads.tapatalk-cdn.com/20170411/9b7326a43ea9207a3e1453b98d979975.jpghttps://uploads.tapatalk-cdn.com/20170411/d37d59e5dca297c0e4f883a87c02d2c6.jpg

Flatworms. :thumbdown

If the corals can be removed with ease a quick freshwater dip will have the flatworms falling off in a matter of seconds. If not, then you might want to get some airline tubing and siphon out what you can. Using chemicals like Flatwork eXit is another option too. The link below discusses all this in detail I believe.

Thanks. I will check the link but just purchased a coris wrasse and an arrow crab. My LFS stocks PraziPro ut hope I wont have to go to that extreme.
