Any know why my black diamond rays white spots turn a bit yellow or tan? My water parameters are good. I read somewhere that if you turn on you lights too much, it will turn a little yellow/tan
Do you have pictures?
Are we talking about dirty spot syndrome here or are the spots uniform but off white? some P13 develop dirty spotting as they mature some do not, if the spots remain clean after 3-4 years then they usually stay that way in my experience.
