Scroll down through the threads to June 23, and read the posts from there. If that doesn't give you all of the information you want, it should give you some more specific questions to ask.
I believe everyone deserves personal answers, but general set-ups are discussed on a weekly basis, so we tend to repeat ourselves much too often for own comfort when answering them. And those of us who have kept darts for some time and have set up several tanks for them, have a dozen different ideas on how to do it-- most of which work. It's really hard to give you a fool-proof formula.
I thought I'd never say this, but try the Search feature and read some of the past posts on setting up a dart tank, if the most recent suggestion (June 23) is not what you want to do.
Then, don't go away-- come back and we can help you clear up any confusions. You can really do a huge variety of things, depending upon tank size, the species of dart frogs you are interested in, and your budget.
