The beak looks like amphidinium.
Can someone help with identification and a question? There is a small brown dusting in the sand, but today when cleaning the chaeto, I found part of it covered with the brown goop and air bubbles. I took a sample of it and put it under the microscope. I have to say that these guys where not the majority of the organisms, there was a pletora of pods, nematods among others. The question I have is besides increasing PO4 (currently 0.02) and NO3 (currently at 5ppm). How do I increase biodiversity in the system [which bact in a bottle, live rock (started with dry rocks), fiji mud, more amphipods]?

I went with live rock from a very old system. I won't say it changed anything overnight, but has kept me clear since.
