Calcium, Alk, and MAG=Elos or Salifert (I heard red sea is also good for mag)
nitrate=Elos, Salifert or tropic marin
phosphates=DD Merk, Hach, maybe elos.....

Elos hands down the easiest test kits ive ever used and give accurate results

I use Hanna checkers for PO4, Alk, and Ca. The rest Salifert. The Hanna checkers take a little getting used to, but once you figure them out they're pretty nice to have. People do complain about the Ca checker alot because it is a real pain to get it to take a reading at first if you don't measure carefully because it measures a very small amount of sample water. Either way the Salifert kits are pretty accurate IMO. I will say I would avoid API with whatever choice you make.
