Not sure from the video what this is supposed to do, but there is no substitute for setting up a separate small breeding tank for your fish - just remove the adults after spawning.
Just a tip - do not move the eggs as they are spawned. Once they are fertilised, the eggs are very delicate up until they have split to 64 cells. Any vibration/movement up to this point can shake the cells apart and the developing egg will die.
