Hello everyone.. i live in central florida, have a small pond (probably
80x30) and just in the last 2-3 months a bunch of this plant started
floating on top. its only in one of my 2 ponds though... 3 questions please

- what is this called?
- what chemical can i use to kill it
- will the chemical hurt the fish (standard blue gill, crappie, small bass, turtles, etc)

thanks for the help!
