Are you using the test strips because they are very inaccurate that is my own experience with FW
. Also API is okay Salifert is better as far as Calcium and Alk
go... Those would be your main ones since you are just starting out. You do have Nitrates you can tell just by looking at your tank. They may be low however you definitely have phosphates that need to be rid of. Only reason I know this is because parts of my tank looked like that a while ago. I did have a hair algae problem like I said and am just added some fluval phosphate tonight only until I can get my pheric oxide sponge type media.
