After having Nuvo 16 running for a year, I started to develop cyano problems. About a year ago, I went for ultra low nutrients and couldn't be happier with the results:
On each side (with upgraded caddies):
1 bag of purigen (I stagger change every 3 months)
I have a filter sock mixed with GFO and activated carbon
Eshopps nano skimmer
Media reactor+bio pellets
I still do 20% bi-weekly water changes
My tank is a bit heavier stocked with 2 anemones, 2 clowns, plates, hammer, a war coral, a chalice, and galaxea.
