Good morning. I am sure this is an easy one. The tank is about a year old. The DT shows no signs of it, but the refugium is loaded. I remove it every few days and it comes back even stronger. It is stringy, gooey, and very dark purple/brown/red.

My nitrates are 1 and phosphate is 0. How do I eliminate the growth? Thank you.

Appears to be cyanobacteria. Having a little battle myself to eliminate it, but not overly concerned at moment. :)
