I am looking to get the test kits for my first tank soon and I was wondering what test kits I really need. I am on a budget so I can not get every test kit under the sun. I am planning on doing a mixed nano reef Starting with softies then lps and after a while sps. What test kits do I really need? I so far know I need alkalinity, calcium and magnesium along with phosphate and Nirtate. Do I need more? Are some of those not needed?
