From what I hear they keep the TMP levels low so you can buffer it to your exact parameters. Hence the "Pro" in the name. This is what I do. It can be a pain but my water change water matches my tank water exactly.
I've been seeing a lot of those type of explanations. But what reefer starts off their ALK at 5? I can understand 8, maybe even 7. But 5? Nah I'm not buying the "so you can buffer it up" explanation.
