Thanks Eddie. I was keeping my PO4 at .03-.05 for over 2 years in my mixed reef. I didn’t have any issues with algae or cyano. I’ve recently had it around .08-.10 and I have cyano issues mainly. My corals have very nice color though so I’ll keep it at this new level for a while and see how it goes.
Hi Ryan's Reef, as I said on this video check your reef and if you're not getting algae and corals are happy that's what your target would be. Although, always try to keep it low, but not as the community standards are, but close. Eddie
