In my opinion it really depends more on your system and livestock than anything.
I’ve been in the hobby a good 15 years. When I had SPS trying to eliminate all nutrients back in the day, I never had much success growing cheato in a sump.
Now I’m doing softies, over feeding my tank feeding coral, and my cheato grows wild full of copepods and amphipods. After a year of this, I’m not having any problems with byropsis or cyno. I wouldn’t feed corals or tank heavily without cheato to absorb excess nutrients.
