You shouldn't need it now that the eggs have hatched. They will wriggle for five or so days, just keep the water circulating.
Thanks then I will save it for next time. Some eggs got fungus but still got around 100 - 150 wigglers
As soon as they all leave the stone the eggs was attacked to I removed it along with the bad eggs
