Help with some advice

I bought a mexican cervesa kit today from my homebrew store and the guy there said to add 1 liter of tonic water in place of some of the regular water. He felt this is what was missing from the kit. Does this sound right! Thanks

That sounds crazy. Tonic water or bottled water? I mean, bottled spring water is a good water to use for brewing, but I can't imagine why someone would specifically suggest tonic water.

What was the kit?

it a kit for a corona recipe from midwest supplies. I thought it was strange to!
