For me it's a mature tank with mature live rock. My water tests show very low N and P without ever running any GFO or carbon dosing.

Cyano growth is difficult to determine cause. We don't always know the cause. It isn't always nutrient related either. Flow is another factor.


Current Tank Info: 125 in-wall , 40b sump. 6 bulb T5. ASM G2 skimmer. LPS and leathers
