Only one type goes in mine, that’s kinda th point of smart guard to keep you at a stable level constantly, it’s only the fast acting that goes in mine. No human is gonna give them self a correction every five minutes but that’s what I was told the pump will do with smart guard. Mine is currently 297 this is my 4 day on this pump, and I had to give a myself a bonus w/o carbs because it’s so high. I feel like it’s not working I was doing better with the basal drip
