What will I have to do?You’ll need to do a few things....
Well I have the 110 ext. these papers do not show me how to use the device internallyI’m a little slow.....
Yea so if I sat it in there just let the water flow in?I misunderstood what your asking.....I see you want to use it in your sump, I thought you meant you wanted to use it externally.
If you have the sump space...I guess you could just sit it in there and run it the way you would externally, although I’ve never heard of anyone doing that.
It works internally and externallyYea so if I sat it in there just let the water flow in?
I’m trieng to find out how it works internallyIt works internally and externally
So I place the feed pump in sump with the skimmer and let it runYou still need the feed pump
I had a manifold off my return and fed it off that’s when I had my reefer 250

Hey thanks you guys. I think I’m going to need a little more insight to help me out though. Cause the guy from the aquarium store hooked a hose from under the waste jar into the inlet in the bottom of the skimmer saying that it all works together and the pump on the other side would let in the water.Yes.
I ran this exact same skimmer in my reefer and it was in sump.
Nice thing about the externals is that they aren’t picky about water level.
Just feed it with a pump in the sump, or tee it off of your return. I’d shoot for 400-600 gph. Then you use the gate valve to adjust the height in the skimmer
You can then use the plumbing that came with it to discharge under the waterline. Just remember to use the vertical vent pipe if you do discharge under the water. Otherwise it creates a slight siphon effect. But if the outlet pipe is only partially submerged then you should be ok without it.
