Np Bacto Pellets vs Np Bacto Tricks

[Otago]

What reasons would I choose one of these over the other ? I can see they run in different types of reactors but is there a functional difference between the effects of them ?

I heard back from Hans-Werner Balling and he says they are made from the same material and just designed for different reactors with not too much difference in the application between them. Hope that helps the next person googling this!
