Reefing newb
Ok my tank is almost 4 months old now, i have been having diatoms on the substrate for a several weeks which i know is normal for a new tank, but the past week i notice that in a few areas the diatoms looks like a light lavender color it still has the same texture as diatoms just diferent color, does diatoms turn this color??? or is this something else now?? it seems to be more prominant when the lights are on by the end of the day and seems to partialy go away when lights have been out over night like my diatoms does.
