there isn't really a good way to get them to transform into frogs faster. Just keep the water near the right temp, for tadpoles and other aquatic creatures its usually around 72 degrees, with a small margin of difference. Just don't get it too high or it will cook the tadpole. also got to keep the water PH level at a certain level, if your on well water and there are absolutely no chemicals in the water you should be fine. you should be able the get the water tested at your local pet store. also any chance on a picture?
