It is not C. x willisii. It doesn't not get that large ever.
It always remains green as well. C x willisi is a natural hybrid hence the
cross( x ) in the name.

If you do say 20 % or less at a time perhaps even less in your case you
should have problem(s). When you do the 50% uprooting and not water change
after etc...your asking for it.

I don't vacuum, since there's hardly a square inch

No, they will escape out of the pot for sure.

Key word: "reputed". This one is a weed for you:) I would not worry as I
have used this procedure for many years. It causes more harm to remove the
entire group than a few escapees.
With the likely species you have, you should not have to worry about how
sensitive it is. Some are but most you find in the aquarium trade are not.

That's the idea. Maintain the original group and cull the daughters.
Hope this helps,
