I've seen similar intensely red plants in a lake in Southern Vermont. Very lovely actually. I brought some back and after a week they established in an aquarium and completely lost the red colour. I assumed that it was possibly to do with the NO3 dosing I was doing. I did not test the lakewater, but the runoff was limited, algae was not present to any degreee, it was not a eutrophic system and it was very well established with Eurasian milfoil, ***Potamogeton**** (corrected) sp. etc.
