So I'm gonna be stepping up my coral game here soon. What kind of tests do I need to pick up and what company do you prefer? I have the API saltwater master test kit (pH, ammonia, nitrite and nitrate) , But what about calcium, alkalinity, iodine, magnesium, phosphate, etc. Its going to be just a softie and LPS tank for now. Eventually I'll break into SPS but prob not for another 6 months...
