I dont believe you need to supplement anything in a tank as young as yours. Regular water changes with a good salt mix will provide all the elements a
FOWLR tank needs. I would personally put more trust in a person like RHF (who isn't paid for his work) versus the
LFS that is in business to sell stuff.
I'm not saying that your
LFS is bad, but they (and SeaChem) should not be advocating you to dump stuff into your tank with out knowing if it is needed.
