What Would Be A Good Way

To filter 2 gallons or less of Saltwater?

Its for my hermit crab since he likes to drink and bath in fresh and saltwater I thought it would be good to setup small pools of both types of water and have them filtered between changes.

I am going to use an air pump and a small chunk of filter pad in a tube for the freshwater side. would this alos work for the saltwater side?

Sure, I dont see why not...you are basically building 2 ghetto sponge filters then?
