Gen-X GX4100 Issues

Pump can be found here

I have this pump pushing my modified Berlin skimmer. Unfortunatly, while it works great for the first couple of days when hooked in, the flow rate/venturi action slowly degrades. However, if I disconnect the pump from the skimmer, then reattach, the flow goes back to normal for another couple of days. It becomes this cyclical task of me unhooking the pump once or twice a week. Can anyone conjure up what might be going on? No Caluerpa or any macro (or anything) is getting clogged in the pump. I have it running through 2 X 2" PVC flex with a 90 bend adapter, again, nothing is clogged in this. This then goes into a kent's venturi and up into the skimmer.

I can't figure it out, any ideas?

Thanks
Scott T.

Is the actual flow rate slowing down or just the bubbling?
I know the venturi's clog fairly easily, maybe have it hooked up to a tube so you can let it suck some water through the venturi to clear the salt crud?
FWIW I've noticed a lot of submersible magnetic drive pumps will slow down after a few eeks of running, shutting them off and cleaning them out restores the flow rate.
I don't know why this is...
Sorry not much help :)
