Hopefully these are good enough pictures? Waiting on the phone mount to show up. No slides either so just using glass from a picture frame 
Surface scum samples
Sample from right at sand bed where mostly it’s growing
^^^ some type of worm?
Here’s the current sand bed
Any ideas? Assuming Dino’s? Though I’ve kept nutrients present. Usually NO3 10-15ppm and PO4 .12 I’ve already had two waves of Dino’s in the past from nutrients crashing. This time it seems different and really only on the sand and a surface scum
