If no one other than yourself is interested in tadpole project and you will be away; then maybe it's better to leave them in the kiddie pool and let nature take it from there. It will take about a month for tads to morph out. As long as pool does not dry and they can get some algae, rotifers, etc. should be OK. Do not add straight tap water to pool, it needs to be dechlorinated. Good luck !
