Rarewon yeah i know but purple up helps it once there is coralline in the tank correct?
My tank had 0 coralline until about 2 months ago when the tank hit 8m old. Now its all over the place. I have 0 in glass though since I bought the mag-float scraper and im in love lol. Also my tank is pretty low nutrients idk why I feed 2 times a day, run 0 carbon or gfo and I can go 7 days w.o cleaning class
What's your secret?
