Just curious as to where my No3 and PO4 are going. I've never been able to maintain Macro, or even nuisance algae in my BC29 with 20g sump. Been having to dose No3 and PO4 . But, Xenia , which I have in my sump, grows like wildfire. Pic taken after harvesting about twice as much of it, which was about a months growth. Also, situation was the same before adding the Marine Pure block .
