Need approval and suggestions on my new tank setup please

[Laurie]

I am getting tadpoles soon (mostly tree frogs) and I've read so many different direions on care and habitat that I just need to know if this setting will be fine for my new tadpoles, and when they grow into frogs. I filled the tank with distilled water for the new tadpoles and a filter. I have a gradual ramp for them to get to land when they get to be little froggies. I just read on this forum that I may need a heat lamp when my tadpoles turn into frogs? I have live plants on the land side and fake ones on the pond side. This is a 55 gallon tank, by the way.
