I think the kid (Leo) knows what he's doing as far as buying all that water.
RODI vs Nutrawater.

It's not.
Cause I was question why didn't he just mix salt. But whatever
So the difference is with Nurti water you can actually start your tank quicker! Which is what I'm trying to do! Unlike some people I don't have a system to mix water, not for now! At the end of the day, even if I called 3x or 10x it was to assure i would be able to purchase the item and not waste my time going. But I guess if it takes a Business owner to lie to get customer just to come, he it worked!
Nutri won't start your tank faster the bacteria involved in the nitrification cycle and those involved denitrifiaction cycle are benthic,they colonize surfaces like live rock and substrate. They also use oxygen. I doubt much if any useful or viable bacteria come in the packaged water.
