The feed line is 1", but I have it dialed way back. I've read that 300-400 gph is the proper flow rate. On RC they seem to think that is even a bit much (increase dwell time). I agree. I'm probably running a little under the 300 gph mark.
You should see the bubble size though.... Incredible!! SO TINY. It's creamy. I think the skimmer is just about ready to kick in.
I also have the Kill-A-Watt hooked up to the Dart. It reads between 95-101 watts pretty steady.
Also, I'm curious to see what happens the first time my Waste Container fills up? I'm hoping it shuts the air down in the skimmer, but I don't know.... the cap is not secured down. It is very heavy though!
