What Salt Mix Do I Use?

This was recorded very early in the morning and boy!...do I sound tired! Sorry about that. I really thought I was fully awake! I didnt realize how bad it sounded until I listened to it later. I have ALOT of children and don't always get enough sleep. :) Anyways today I was answering a question that was asked, what salt do I use and why. Pray all is going well with your tanks! Blessings and Happy Reefing!
