what supplements would you use

[reefnut]

I am thinking of a 33 gal with a few beginner corals.im planning on around 160 watts of compact flourescents with lr and a lsb.i dont want to add too many chemicals but i want my corals to grow and be healthy.so im planning on using kalkwasser,coral accel and phyto.I only want to add one more for trace elements.So what would be the best bet for the health of my system?Is there a good"multi-vitamin"?it seems that every bottle i read list four or five others that i should be adding as well.I plan on doing around 5-7 gallon water changes every two weeks.
