I've got the same stuff in my tank. I don't know the ID, but I am attributing it to some organic soil beneath my substrate coupled with "too high" micro-nutrient fertilizing...especially since I'm getting micros from the soil underlayer.
I noticed you are dosing all micros currently. That may be the problem. Once you start the PPS pro it will help, but being patient with it will also help. These things just take time.
