Hello and thanks in advance.
I am wondering if there are sponges that would be safe to put into my dumpy frog enclosure. I of course know that the packaged yellow kitchen sponges are out of the question because they already have soap in them.

My situation is this:
12x12x18 zoo med terrarium has small river rocks in the bottom with a soft mesh over the top with water in the bottom.
Problem is that I got a fogger and the condensation is filling the tank up to the point of overflowing. I'm looking for an easy way to soak up the water so I don't have to worry about it overflowing while im at work and so I don't have to tote water out of it every other day.

Any ideas?
