Questions about egg collector

I was wondering if anyone had suggestions for improving my egg collector as it doesn't seem like it's working strong enough to pull in much off the surface. I'll add a picture later but I'm using the airlift style, with a PVC pipe plumbed through a 2 quart bucket with 400 micon screen on the bucket and some pipe insulation to keep it floating. I have the inlet surface skimming pipe cut at 45 degrees to give me a little room for error as for water level. I'm using 1" pvc and a whisper air pump with a cheap blue amazon airstone. I know the suction doesn't need to be great but this seems like its fighting just to get going. Almost like a wave action where it pulls it down into the tube but then can't keep going and it comes back up. More air may fix the problem but I wasn't sure if I should increase or decrease the PVC size. Decreasing could increase velocity but I'm not sure if there would be enough water to move,and increasing could be the exact opposite. If anyone has suggestions or knows a better way please let me know. Also I have a 3d printer and am familiar with modeling software so if someone has an idea for a design but can't build it maybe I could try modeling it and printing it and we could make it available to the group. Thanks, Bill

I believe all you really need to do is remove the airstone. Larger bubbles will create more of a lifting effect as opposed to smaller bubbles (think surface area to diameter, like an oar vs. a stick in water). Also, the inlet for the air bubbler should be placed a little bit above the lowest bend on the vessel side of the collection tube, as reversal could potentially happen with bubbles going in the opposite direction causing backflow/surging.
