Sorry, never answered this and the thread just got bumped, so it deserves an answer. You said:
"I do have received a professional experts opinion, but I keep that for now."
That sounded like you got an answer from someone and were not going to tell us. What I meant was it is best for all of us for us to hear the opinion so we can learn. :)
Well, that went through in the wrong way as I saw the responses.
Reason was I did not mention it prior, I did not want to mislead the opinion of the experts here, or even influence it.
So the sources I reached out to, had a fresh open mindset to start from. Hope that explains it a bit.
Anyways, the source I got that from does not liked to be mentioned here, to avoid to get flooded with emails and requests from hobbyists on this subject.
The ID was actually a common airborne, not usually in marine environment populating fungus. So an adapted "marine" fungus. I was getting lab results to check for for certain Volatile compounds….., Salifert did send me their ORG-anics test, did some Petri dishes etc.
So at the end I had 2 actions.
1. Kill or reduce the fungus
2. Avoid, VOC's, high organics, and perfumes and other soaps etc. that brings in a lot VOC's through the skimmer and drains and so on.
We do not use Yankee candles or other air refreshener, so that was out. However, my Automated Water change system and reservoir was in the laundry room!!! Plenty of perfumes here, no good. Also I did wash routinely my socks in the washing machine 2times with extra rinsing, no good!
So changed my Water change system strategy and later came up with other methods of Trace element management.
Did a DETOX treatment, run activated carbon for 48 hours, and adjusted the skimmer to produce finer bubbles.
Also as I trust Biodigest I poured in a 4x overdose of bacteria.
Then I used Kordon Rid Fungus for 2-3 weeks. I did had to repeat this a month later again, and I did not see any more fungus after that.
Health of all corals improved after 4-5 days, when the slime/fur started to disappear.
Again, in my case it was more a furry type of growth I observed. Not a gel type of growth.
