Ooooh.... keeping SPS without kits.... hold out your hand! Low ca and alk will give slow growth and sometimes RTN if it's chronically low or changed too rapidly... changing a lighting regiment or spectral output usually is the culprit when they lose colour...
It has nothing to do with the Lionfish...

Definitely need to test both. Actually, if anything, if you're going to test just one of Ca or Alk, test Alk. A high or healthy Ca value means nothing if there's no correspondingly balanced Alk value. If you want to think of Ca as the quantification of "how many building blocks are there available to use", then Alk is the quantification of "how much ability do things have to make use of those building blocks." I.e., it doesn't matter much if you have all the lumber sitting in a pile next to you, without tools of any kind, you're not going to build much of a house.
However, as far as colour of SPS goes, it is usually a question of lighting and nutrient levels in addition to good Ca/Alk values.
