Thank you all, I've tried everything short of leaving my CO2
on 24/7 and still cannot seem to rid my tank of this stuff. I keep removing it, cleaning my tank to the point of none being there and within a few days, I see it start appearing again! I know my CO2
levels are good do to my drop checker, I'm dosing EI, I seem to see less when dosing EI rather then the PPS-Pro method. Plants are growing like crazy, look lush and green, I have a power head going along with my spray bar facing down toward the top of the tank so that it creates a strong current. I don't know what else to do!
I thought about removing all the old subtrate (Seachem Flourite) because that where is seems to appear the most, although I have seen some around the holes of my spray bar too, as someone else stated above. I am not beginning to see some on my sword plant leaves. It's so frustrating, I feel that I am never going to see the end of it. I tried dosing Excel, one cap per day, should I start dosing more? Could it be something in my water, a lack of a nutrient or too much of another?
Thanks for all your help, it's very much appreciated.
