I've had the aquarium with live rock for almost three months. I'm almost at the end of the filamentous algae stage, but for a few days now, these brown gelatinous clumps have been growing on the glass bottom (and on some rocks), some almost 2 centimeters long, isolated, others smaller, and others very small clustered together. I thought they were dinoglagellates, but my research hasn't found anything similar.
Does anyone have any idea what they are? And more importantly, how to get rid of them. Thanks.
