Good advice from these reefers.
Here's my take on what supplements to add.
Rob mentioned if you don't test for it don't add it. That's good advice. Here's an expanded version of the same thought. If you
can't test for it don't add it. Do you see the difference? There are many "supplements" out there that the manufacturer makes unbelievable claims about. But if there isn't a test kit for it, how do you know what level is already in your tank. What's too much? What's too little? What research has been done to determine the necessary level or the necessity of it at all?
I've been in this hobby for 59 years (I'm 68 years young) and strictly saltwater for the last 32 years. You will never hear me make claim that I know everything because this end of our hobby is changing faster than I can think. I learn something new daily. You are taking the right track on your education by asking questions here. Congratulations! In the "good old days" we didn't have this luxury!!! It was by trial, error and experimentation. A costly way to learn.
Make regularly scheduled water changes faithfully. Measure Calcium,
PH/Alk, dose with a good two part supplement (Ocean's Blend is the brand I use and recommend) and most importantly keep a critical eye on the general overall health of your livestock. Are your corals looking healthy or are they
bleaching? Are your clams opening up and laying out their mantle? Are your fish swimming around their home or are they listless or jerking around?
Really observe your tank, deeder, not just as a thing of beauty but with a critical eye.
Good luck comes to those that think ahead and make plans to succeed.
Good luck to you, my friend
