Well I last updated February of 2017 so it has been almost a year and a half since I discovered the alcohol source at my clients dental office. Alcohol wipes that were used to wipe chairs and equipment tables between patients.
Stopped using them. Solved.
This was unequivocally the reason and sole source of the slime bacteria that cursed the tank for nearly 2 years.
The tank is now thriving. All coral looks great and fish and inverts are all behaving normally.
If anyone considered a similar problem (VOC's) may be what is causing their slime outbreak, try to vent the room and get the air supply for your skimmer from an outside air source if possible. The improvement is nearly immediate.
Good luck
