Don't think it's a huge issue, you may be able to increase the water level to remove the vortex, or point the nozzle at a different angle.

Ok thanks I have tried pointing different directions only way it stopped was when I had it pointing at the surface more . If I add much more water ot will be very close or touching the top of the tank
