Welcome to Reef2Reef, Chris! Going through the journey of caring for a saltwater aquarium sounds like a great way to spend time with your daughter. There's a plethora of knowledge and resources here, so you came to a wonderful place. Also, don't forget to start a build thread, when you have time, of course; we would love to follow it's progression.
We are glad to have you. Stay safe, and thank you for your service.
