Getting rid of tadpoles on top of vinyl cover

[fairplay13]

We have a vinyl cover for our pool which snaps into the perimeter of the pool (not a safety cover) and we have noticed lots of tadpoles on top of the cover. We are not planning on opening our pool for another few weeks and we are wondering how to kill/get rid of these tadpoles.
Any suggestions?
Thanks.

Are you pumping water off of the top? If rainwater is allowed to sit on top of your cover for any length of time, you'll get tadpoles.

I am going to pump it out.
But I am curious if I was to put chlorine or bleach in the cover if it will eat away at it.
