Question about Reef Octopus DNW-110

[PFoster]

I have emailed coralvue to ask them about why the directions indicate that the skimmer should only be used externally. To be honest I have no idea why the instructions indicate this.

We have lots of customers locally that have used the skimmer internally without any issues. In fact we have a DNW-150 running internally in the sump in our fish system for well over a year now with no issues.

Thanks. It would be good to know what their concerns were about running it in-sump.
