Welcome back to the salty side and we're glad you found us! We all started out clueless at one time and this is definitely a hobby where things are always changing. It sounds like you're off to a good start with your purchases and it sounds like you have a great support network within your family. Nothing good comes from rushing saltwater so you're already in the right frame of mind. Ask as many questions as needed. Heck I didn't even know when freshwater top-offs were needed vs. adding new saltwater so you're probably starting off miles ahead of where I was. Haha. I look forward to watching your tank progress and I'm sure it will be wonderful.
