Hello, about a month ago, I set up my first sump ever. I received this macroalgae from a friend in the hobby (i know this is not recommended, but it was full of pods, and healthy when I received it with no pests). he told me it was "dragons breath" however upon googling and searching, I am not sure that this is even dragons breath? Secondly, the real question here, what would cause it to turn green?? I have had it under 50% blues for a week. it was under higher light, but once I noticed it changing color I dropped the light % in hopes it would help it... I'm not sure if I should even leave it in there at this point, but I will also add my parameters (im doing a fish in cycle, and maybe the parameters are the reason its declining). any suggestions or help would be great! Alk: 9.2, Calcium: 419, Phosphate: 0.29,PH: 8.2, Ammonia: 0ppm, Nitrite: 0ppm, Nitrate: 15ppm, Salinity: 1.025. (I didn't notice till this test, my tank is finally cycled!) i added pics of my system while I waited for the tests to develop, enjoy.
