How to get an object from Poolboss -- Darktonic GameKit

Hi,
I purchased the DTGT a while back and decided to give it a go.
I have 2 questions:
1) I use Poolboss and DTGK Spawners. I have my own health manager on my spawned prefabs, when I have shot them I just "gameObject.SetActive(false); and this returns thing to the pool. Is this ok? it seems to work fine.

2) I have a gun that fires a raytrace and on hit will spawn a bullethole, the bullethole is removed after a short period time. The code for instantiating the bullethole is as follows:

GameObject cloneImpact = Instantiate(impact.GetRandomPrefab(), hit.point, Quaternion.LookRotation(hit.normal)) as GameObject;

How can I get the bulletholes from poolboss? ( I have them pooled already ).
I have tried without any luck the code below:

PoolBoss.SpawnInPool(impact.GetRandomPrefab(), hit.point, Quaternion.LookRotation(hit.normal)) as GameObject;

Thanks
