No3 24
Po4 0.08
Po4 was actually .16 early this month, I started nopox again and carefully dosed some lanthium chloride to get it down. I've been over feeding a bit too help with some aggression, so it wasn't much of a surprise. There isn't really any algae in the display, I guess the tangs take care of it, now that I have a light and frag rack in sump I'm getting algae in sump since there's nothing to keep it in check.
I'm almost out of nopox so need to either order more or switch to vodka/vinegar. Also need to boost alk a little, maybe to 8.
