If it does turn out to be bladderwort I would think seriously about leaving some of it. My pond had it before the Great Muskrat Invasion of 2020.
I pulled a rake load up to see what it was and what was in it, and was astounded at the number of fish fry, snails, bugs, etc. hiding in there.
It also makes some nice shade, which helps to keep the water just a little bit cooler.
