Hello

I am starting my first reef in seven years, and was wondering what supplements I should be considering. I do regular water changes, but in my old system I also supplemented with strontium, iodine, magnesium, and iron (and obviously calcium). I'm not sure what has changed....

Thank you!

all are still used but you always want to test for what you add first.....the only thing thats changed is better lighting, filters, and test tools.......welcome to the forum!

If you're using a good salt mix and running a calcium reactor or using a two part solution you shouldn't need to add calcium or magnesium. Strontium and Iodine I don't test for but I'm guessing the same goes for them too. Ideally the you don't need to add anything aside from top-off water and fish food.
