Thanks all for your reply and my apologizes to those who were involved in some disagreements in effort to help me resolve my problem....
Someone asked about:
Lighting = sunlight (estimate about 80% due to the angles of the windows) - I think it's a good day/night cycle
Skimmer = external (fully in sunlight)
Live stock =
tiny anemone (got from deepwater) (tough guy, doesn't even seem bothered, even after it was viciously attacked by a butterfly fish I kept)..
Neon Velvet Damsel 1 large (got from FastUno) and 1 medium (had for about 6 months) - both died, large fish eye pop white color, refused to eat attempted to quarantine - died, small fish fin rot, ick, eating, then died.
Atlantic blue Tang - nicest fish in the tank (medium size), developed ick, pop-eye, red coloration as in damaged blood vessels, attempted to quarantined, died.
Purple pseudo and clarkii clown (got from nanoreefer22) - both were attempting to scratch themselves against rocks, had ick, clown swiming at top of tank. Was about to quarantine but ick disappeared, purple pseudo seem fine no ick, clown fish no ick, but still attempts to scratch himself on rocks, though not as much.
2 mollies 1 black (born and raised from 30g tank) 1 gold large - both male - no chemistry there...(I know some people will be wondering, if you are familar with mollies)...and they never seem affected..
What I did.[before the outbreak]
- Moving tank, drained all water, kept 50% off the top, drained the rest, (didnot want to loose all the bacteria). 75 Gallon Tank
-All chem check out ok, no nitrates/nitirite/amonia/ph kept at 8.2-8.4, salinity 1.023 (use mangrove plants - excellent filtration of nitrates)
-Water temp brought up to 80 deg, fish placed back in tank, everyone seemed happy
-suspected outbreak, was alreay looking for goby, wrasse and shrimp / deepwater also suggested on this thread
-full outbreak - damsels started dying showing infections (had blue damsel and yellow tails too), posted on Manhattan Reefs for advice....
-Read some of the feedbacks and suggestions you guys posted, all I did was raise the tank 2 deg, the change hasn't fully taken effect as yet but tonight I will check and should be at exactly 82 degrees (still 80 deg high, temp is yellow low and green/blue = high) it was last at 80 green from 80 yellow - LCD thermometer reads that way - weird but it works.....
-ick seems to be disappearing on the pseudo (almost completely) no sign on clarkii which still tries to scratch it self from time to time, both are swimming, hiding and eating....
