I think the plants would be safe if you used prime to treat the water. I do a lot of aquatics and I love prime. It would be best to use RO water for your fogger though. It is definitely easier to keep the humidity up with a solid top rather than a screen top, so I generally prefer a solid top. If the humidity is above 80% you don't need a water bowl but I think that frogs enjoy a good soak every once in a while. The one thing that I would say about the amount of frogs is that it's better to have 3-4 frogs instead of 1-2. I hope you have good luck with your frogs!
