i recently started to get what i believe is cyanobacteria in my tank. Its dark purple in color. Oddly it goes away each night after the lights have been on for about 7 hours(and still on), but returns the next day shortly after the lights come back on. It seems to have started shortly after i began adding Kent garlic to the food to help my hippo tang. Whats the best way to get rid of this that is reef safe? also, is it common for the cyano to just totally disappear after 7 hours of light?
thanks
