Hi I got pulsing Xenia and GSP from friends tank .I place it 12hr before after that night I switched off the light .GSP starts to come out ,but Xenia is not looking good ,I have diy Marine blue light with 30watss and nano tank with 90liters and medium flow from return no wavemakers added.Before turing on the light Xenia is flat now stands off after on the lights.I've attached a file for reference and how much Max and min nitrate and phosphate these two can handle.In before I have green and brown alage in my tank
