    The best spectrum colors for Refugium

    After installed UAS and ATS my refugium empty no macroalgaes growing, all fade off, probably my UAS and ATS consume nutrient,
    but after I start change water frequently its look from my refugium the rock grow macroalgae again slowly while UAS and ATS still growing.
    I want to start to focus again growing macroalgae in my refugium for the best light using LED, but still confuse abaut spectrum wavelenght and how many kelvin they need. Now I use mix 6.5k 455nm 620nm,

    Anyone know which ones is the best for growing macroalgae in refugium ??
    they need mix colors or what ?
    It is the same need spectrum like we build light for ATS or UAS ???

    Yes, it's the same, people have now started to use the red blue growlights in refugiums. Cheato seems to grow well in it.
