Juice one Blood Orange and the Lime, set aside.
In a small pitcher add a scoop of ice, pour in the tequila, then the blood orange and lime juice. Stir to combine. Give the juice a little taste and if you want to add a little sweetness, add in 1 teaspoon of agave nectar.
If desired, rim half of the glasses with salt and add some ice to each glass. Pour the Blood Orange mixture from the small pitcher into each glass leaving about 1 inch of space to the top of the glass. Top with Seltzer Water.
