You can go up to an entire month without changing it as long as you keep up with waste removal and if it doesn't become overly saturated with water from the frog splashing around I. the water dish. oversaturation means stagnant water sitting beneath the substrate and would need to be changed out.

If there is a false bottom in the tank you can easily go a month without changing the substrate, but the same tasks apply. Also check by smelling the substrate. Good substrate smells like fresh dirt so if it smells like fungi, mildew, it fouled water change it immediately.

Hope that helps.
