Is dosing needed for corals???

[Batmanjay28]

I have around 20 mushrooms, red, green, orange colored ones, a branching frogspawn, a bubbletip anemone, and a leather coral.

The question is do I need to add Calcium, Strontium, Trace Elements for the coral and iodine and trace elements for the muchrooms? And if I do need dose can someone explain to me why. THanks ANy other suggestions would be great too.

I could be wrong, but I believe most of those elements are already found in the salt mix. Of course, which salt mix you use would make a difference in how much of each element is there.

Depending on the salt mix you use and the calcium demand of your tank, you may need to add calcium. The only way to know is to test for it, add if needed, and monitor consumption. I need to add calcium 3x a week to keep up with demand in our tank, and maintain alkalinity levels via alkalinity buffer in our auto top-off reservoir.

I've yet to find a need to dose strontium, iodine, or a trace elements mix in our tank of softies and LPS. I use to dose iodine regularly, but since stopping over 6 months ago, I've yet to notice any difference.

Ditto to what the above posters wrote. A good salt mix may supply all that you need without buffering. If you do add supplements do so with testing so you don't overdose. I'm personally trying to avoid supplements and with stocking light on stony corals I'm hoping to get away with it.
