Reef Octopus Skimmer

[chemmjm]

Just purchased a reef octopus skimmer. Connected to my Precision Marine skimmer overflow that has the ping pong ball to stop the skimmer in the event the overflow fills. It does not work with the reef octopus skimmer. I would suspect because the top of the skimmer does not screw down like the PM Bullet 1 and its doesnt have a vacuum. Any suggestions.

Thanks
