I’m kind of in the same boat. Phos (.4) and nitrate (26) high, but tank looks great and everything has been stable, ie, no coral die off or fish deaths in 6-8 months. I too would like to get both down. I think if I could ge them down, it might help with pesky cyano outbreaks I’m seeing.
But other than the few spots of cyano I keep vacuuming, everything else seems better than ever.
I do feed a lot, auto fish feeder runs a minute every few hours, but I have a school of lyre tails that need constant feeding.
honestly I stopped checking phos and nitrate as frequently as I used to. I only check it now, every 6 weeks or so. And when I send out icp tests every few months.
