I don’t honestly know… If you have a spare heat lamp around, maybe rigging something up under the spare lamp, in a different tub/tank would help? Spreading it thinly will also help it dry out quicker
Spread it out on a cookie sheet and pop it in the oven on a low temp for a few hours. Stir it around now and then, and let it cool before use. Should bake all that moisture right out.
