I agree with Cecil, I have seen lots and lots of Chara and a similar genus called Nitella. I have never seen it float. The vascular features are not such that will allow it to float similar to alot of other submerged vegetation. The only way that I know it could float is if it had FA attached or was somehow trapping air or gas bubbles. IMO you have your plants misidentified or TX Chara is a lot different that regular Chara. Some bushy pond weeds look a lot like Chara. Although bushy pond weed also typically sinks when dislodged. A close-up photo of Chara that floated would be very interesting and educational for Cecil and I to see.
