A oily looking light green surface film showed up late in the evening and was still present this morning. It was streak-ish in nature compared to the clouds of oil-like film from 7/10. I suspect the streaks were from the 24/7 aeration where as the aeration was only running at night when the 7/10 film appeared. What's next? I'll have to wait and see.


Fish on!,
