Honestly I'm in over my head for my knowledge base, but I know I can learn and continue to enjoy the hobby more than ever. I don't know how to check or what to have my calcium, magnesium, etc at. Coral specific ideas. I have never had coral or plants or copepods or amphipods... Well I probably had pods but I never needed to care about them like I do now. I don't even know how established the tank was when I got it (how old) though I did do a complete water cycle /change when I moved it to my house. So first question how to I check calcium, magnesium, what else do I need to check? What should I ensure those levels be at or around? What's the best way to supliment them into the tank? Are there any other coral care instructions I might now know about? The fish are all happy and healthy, I have a pretty good handle on them. What are some suggested inverts? I basicly have none besides maybe like 15 snails and a few white leg hermits...
