Many bubbles with Medtronic bomb

Hello,
I also have micro bubble problems.They appear when loading insulin from the ball and it is impossible for me to remove them.I have noticed that in the last reservoirs, when I change them, they have a larger bubble formed.I have always had insulin at room temperature, I suppose they are formed to pass the insulin too fast to the reservoir.
Another thing that I see is that in the tub there appear whiter spots, which look like bubbles, but that would say that they are not since putting a bolus do not move.Does that happen to you?

@Maik_dyk, yes, I have seen them too, it seems like a plastic itself ... I have not observed that they give problems.;;)

I think it's insulin problem.I use feathers and in 41 years as many bubbles had been done as now.Both in winter and summer
