. Hope it helps. I'm really sorry about your frog.
"The aquarium and most accessories can be sterilized with a 10% bleach solution (use a 5% solution to avoid damaging acrylic tanks). Rinse very well. Dry them out completely and allow them to stay dry for at least 12 hours. Any non-frog tank mates such as fish, invertebrates or live plants need to be housed away from the frogs for 2 to 3 months. The plants could be properly disposed of instead. The gravel can be baked in an oven at 350 to 400°F for about an hour or so. The inner temp must reach near 200°F."
This is all exactly what I would suggest, although if you've got natural rocks or sand you can go up to 500°F. Baking on a cookie sheet is a good way to do it, but wet rock can rust metal while baking, so line the cookie sheet with foil before putting anything on it.
The bleached tank and accessories should be left outside in a sunny spot for those 12 hours; the sun will break down any remaining bleach traces and render it harmless.
