My tank (15g) is finally cycled and seems stable as far as that goes. I used API for the cycle. I feel like my salinity testers are sufficient for now(refractometer and a Hanna digital) but I’m wondering what higher performing test kits I should start getting. In July I plan to start adding mostly zoas and a couple of LPS as well as a gorgonian. What parameters do I need to start looking at now. I plan on doing weekly water changes of about 2.5 gallons. Thanks for any thoughts on this matter.
