I have 15 colonies of sps (pocillipora, acro's, and monties) that are all showing signs of brown jelly infection. Actually most of them are more than half covered and dieing. The other half of the corals still have some tissue on them. Am, trites, and trates are all 0. PH runs 7.8 to 8, temp 78 to 80. Any treatment suggestions would be welcome. Tank specs are in my profile.
