Miele UltraPhase 2-Component Detergent for Whites and Colors Aqua Fragrance (UltraPhase 1&2 Bundle)

How many loads of laundry will these do?

Before installation do you need to peel off the metal foil on the spout? I had been jamming it in with it on but am getting errors now.

what is the difference between 1 and 2.?When to use one vs the other?

Does this product only contain one bottle of Ultra Phase 1?
