New Skimmer Troubles

[Kronk]

I bought an Octopus BH100 skimmer but I am having some issues setting it up... it produces large bubbles into the reaction chamber not fine ones which means no foam. Curious as to why a skimmer would do this? is there not enough airflow? too much?

Also it seems like the pump kind of chugs the air into the reaction chamber instead of a steady flow. I am pretty sure the pump is primed right I cut off the air until there were no bubbles going into the reaction chamber then opened it up.

Any help would be appreciated.

Thanks,
Ken
