Water depth for Octopus NW110 skimmer?

[mjsnook]

Doe anyone know what the recommended water depth is for an Octopus Needle Wheel 100 skimmer is? I looked through the whopping 1 page of documentation that came with it and cannot find any information.

Thanks,

Mike

bump...still looking for information. Skimmer is Needle Wheel 110 not a 100.

Thanks,
