The first and second pics I believe is clado, it comes out in clumps, easy to pull off logs and other objects and feels like a ball of soft hair. The third and forth pics are what I was asking about feels like thread harder than the other algea to remove I have pulled whole plants out tring to remove with a filter brush. Now the clado is low nitrate and low co2 which I find hard to believe as the last time I tested it was like 60 ppm now I didn't calibrate the test.
