Does anyone have trouble with their return nozzles sucking air?

Like the title, anyone have issues with the return nozzles creating vortexes/sucking air from the surface? No matter how many ways I try to adjust the nozzles and angle them, I don't seem to have luck. It is absolutely driving me insane. Let's hear it.

Use loc-line to extend it so you can bend it lower from the surface to stop the vortex air sucking.

Also use a side flow nozzle to break the syphon so most of the water won't end up in your sump due to lowering of the end of the return nozzle when the return pump is powered down.

Except I drilled a small hole on the underside of one of the locline pieces for a siphon break.
