I was wondering if anyone could help me identify this brown stringy algae in my tank. Tank is about 8 months old, so originally I thought it was just a regular diatom outbreak and I'd be fine after the nutrients depleted. It's been two months, and while it's gotten better, I'm wondering if these are Dinos instead and I may need to take a different approach. It grows on the sand bed, tank glass, and rocks. Slimy to the touch and detaches from the rocks/glass with ease. They generate air bubbles on occasion too. Thanks in advance for any insights.
