Can someone please help ID the predominate algae seen below? It's mostly on the sand bed and appears to go away to some degree at night.
So far, I have identified Pennate Diatoms and Amphidinum Dinos, but I cannot get a handle on the other brown translucent organism, which seems to be the juggernaut in my samples. Is this also a type of dino or perhaps a diatom? I had nutrients bottom out around the 5-month mark of the system, and currently, the nitrates are up to 7.1 ppm, and Phophapates = 0.09.
Any help is much appreciated.
