You don't need to test for iodine unless you dose it and if you do test it, the test kit is probably wrong as the iodine test kits are inaccurate. Zoos depending on species like low to medium flow and can be acclimated to almost any lighting provided its not like a 60w kitchen light yah know

Like stated about you do want to test for PH, Cal, Alk, Nitrite, Nitrate, Ammonia...Phos and copper are ones that sure, do help, but are not neccesary.
There should be no reason to test for nitrites or amonia if your system is established. Trates are a good idea to test for but its not an every day thing. Once you learn your tanks maintanence cycle you should be able to test once in a while for preventitive measure and be ok. Calk, alk, and pH are essential things to test for. Calc is one of the essential elements used for coral growth, and if you dose calk you will want to test for magnesium. But in the beginning stages IMO get a calc, alk, pH, and nitrate tests and go from there. Always check your salinity too. All the others I would only test for if I started seeing a problem. IMO.
