OK, so I just got my new RSM set up. I filled with tap water just to make sure there are no leaks, and all pumps work ok. Making my RO water now. When it is done, I will drain the tap water and fill with my RO water. After that point, I am not 100% sure my next step. Do I need to put salt in right away, or wait a few days? After I put my salt in, then what, live rock right away??
