Are the plants growing well otherwise?  If so, I wouldn't worry 
about them.  Tie them down with monofilament fishing line instead. 
 It can't be seen under water, and will not rot and let the plants 
float free.

I grow a variety of aquatic plants (submerged) in containers on 
the windowsill.  There are no fish in these containers because of 
their small size.  The plants get their nutrients from the soil in 
the bottom of the containers.  The windows face south, and in the 
winter get direct sun for most of the day.  I have no problem with 
algae in any of these containers.  It doesn't matter how much 
light you apply, (either in intensity or duration) if the 
nutrients are not available, algae can't grow.  Algae is just 
another plant, albeit one we'd rather avoid.<g>
