What do you need to raise African Clawed frog tadpoles?

A question, did you use water from the taps to refill that tubaware because if you did, tadpoles are very vulnerable to the chemicals used in tapwater. Also after a month you may want to put a heat lamp slightly above the water so it heats up a little. Also you may want to add a rock or somthing that the tadpoles can climb up on when they start to from legs. Hope this helps!
