RSR 425 return nozzle syphon

[TheBear78]

Hello.
I am a few weeks into ownership of a RSR 425 XL V3 and have a question regarding the return nozzle. I am using the original Y piece return nozzle but when I turn off the pump for feeding it gurgles and pops like mad while the water level settles.
It is currently angled down as far as possible but if I angle it upwards enough for the gurgling to stop (due to the siphoning effect) it draws air from the surface when the pump is running. Obviously I can manually adjust it each time I turn the pump off but don't really want to wear out the joint.
Does everyone have this problem?
I have also considered fitting an aftermarket nozzle with the loc-line sections for increased directional control but worry that if the nozzles are even lower it will just syphon more.

Thank you for any help.

Actually, I’ve ordered something to use loc line so I can curve the tube up then down so the siphon isn’t as bad.

Thank you. I am reluctant to keep fiddling each time I turn off the return pump but maybe there is no other way, or just accept the noise!
I am quite keen to incorporate one of the loc-line nozzles so I can direct the flow into a couple of dead spots but if it causes a worse siphoning effect I'll just have to rely on the gyre pump to stir everything up.

I don't understand how the outflow nozzle "draws air from the surface".
As for the siphon, you can drill a hole on the underside of a higher point of the return line (in the tank) so it will stop the siphon once the water drops below that point.
*You will always have some gurgling when you stop the pump because it WILL siphon a bit. The key (and reason for a siphon break) is to keep the siphon from drawing more water into the sump than it can hold. Otherwise, it's just something you have to deal with.

Yes, you will have to accept the noise.
