As AMCARRIG stated perfectly, with your bioload, I don't really see the need to add supplements to your tank. The Reef Crystals salt mix is comporable to Kent's salt in that it has added supplements above most other salt brands. Especially calcium and strontium, however, trace minerals are also add to Kent's and Reef Crystals salt.
If you had a larger quantity of corals and clams, then I would think about adding iodine, strontium and kalkwasser(calcium).
Another thing to keep in mind is that alot of the different brands of synthetic salt mixes on the market are in fact made in the same lab/factories!
Best of luck with your tank...Keep those corals growing! _________ 125gal.w/Mag9.5 return(dual megaflow)>Mag7 pump Aqua Cev180skimmer.Wave2k Hamilton Reefstar(2)250watthqi(mh)pend.a Yellow, Naso Tang Red Lip Blenny Percula Clown Demoiselles Niger Trigger F.
