I use to keep a FOWLR system. I didn't dose anything at all. It went auto pilot for 2 yrs before decomm.
Now i have a coral nano tank, and the only additives i add are colour enhancers from grotech. Rest is considered coral food or amino acids, I'm not counting balling method as a form as addictive.
End of the day, keep your water clean (filtration, sump maintenance, regular water changes) , good husbandry and know your fish well (i.e its diet, compatibility, and natural behaviour)
I'm not saying all additives are bad. But you need to understand what you are putting in your tank. Maybe other bros have had good success with certain additives and would like to share.
