Cabomba... How to scape if no soil in tank?

[Stitch]

I was given a few stems of cabomba recently.
However, I do not use soil and soil medium in the tank.
So what can I do with the cabomba?

Tie to log? Any suggestion?
It is left floating in the tank now and the leaves keep falling. Choking on my filter inlet.

Do you have any form of substrate? I believe that if it does not take root, it will disintegrate after a while.

Cabomba can survive like hornwort from my experience with them, but they don't grow nicely that way, just floating around in midwater.
Better to have some soil, otherwise the cabomba does not grow new shoots...and just gets longer and longer

Is it not possible to tie to a piece of log and still make it nice? Mine is a bare tank thus would be challenging now to put in soil medium.

I think it is possible since cabomba has no roots and it grows via stem elongation mechanism sprouting more needle like leaves. But planting in soil may give it more nutrients that it requires for better growth. Or else with a lack of nutrients or growing factors, the leaves will shed and it will become very messy. If you want to weigh it down, perhaps you can wrap a layer of cotton wool around it and then a strip of metal around it to weigh it down.
