To counter this you have to feed them with amino acids and various other supplements to maintain colour. It's a very delicate balance act. Stave them then feed them just enough so that they look super awesome. Many corals in the ocean reefs are naturally not as colourful as what we see in ULNS reef tanks.

yeah its a teetor totter (?) and delicate , so some steps need to be taken to keep them stable.
like i say though i dont find the need t go ULNS you get great colors, growth and overall livestock health is just fine in a low range system
youll still be nil for nitrates but at least its not sterile inda nil lol
