Based on articles and posts I've read, Cyanobacteria thrives for a few reasons. But the common denominator that comes up in almost every article I've read is an imbalance in the tank where Cyanobacteria outcompetes for the nutrients available in the tank.
Both NO3 and PO4 have been at undetectable levels in my tank for many months. During this time, Cyano has thrived. In an effort to raise nutrients, I've shut down my skimmer and removed all Chaetomorpha from the refugium. But still, no rise in nutrients.
Am I right in concluding that the Cyanobacteria is consuming the nutrients?
What competes with Cyano for the tank nutrients. What do I need to add?
