The chemical/hormone fact is true.
I change 10% of the tank water daily with aged water & have achieved 90% + results with this method

Sounds like the tadpoles were used to the dirty water and when you changed it all they went into shock as they were not use to such the clean water.

Next time make sure you only take out half the water and leave the other half in and just top it up with the new water.

Two ways to kill tadpoles; a; Use Tapwater and B; give them a dramatic temperature change.

I have used much the same process as above in the past with my green tree's. Only changing small amounts at a time and using aged water seems to be the key.

I originaly did not change the water at all but found that only 2 -5 would morph without regular water changes.
