I heard that total darkness for several days can kill planaria.
Personally I have doubt about this but is this possible?

No; it will likely have zero affect on them. Sorry. A blackout period is better suited for relieving cyanobacteria outbreaks.

although, from watching them, they do come out to catch some rays every day, then go away at night..

i have no idea what bearing that has on this question though :D
