remove as much of the sponge as you can and re-plant.
The sponge really isn't dangerous per-say. it just makes it harder for the plants to grow.
I kind of did an experiment with me amazon swords, with 1 I got nearly all the sponge out and with the other the roots were so grown into it that it was hard to get any out. Guess which one grew faster? The one without the sponge lol.
