That the idea. I have a 8 port air pump very much like this one, and use these air stones. They have others, such as the stainless steel ones but they seem to clog up after a while. The standard stone type will only last about as long as it takes you to install them as the bio melts the glue and they fall apart like a sugar cube dropped into a cup of Tea.

I use the sun for my drying. Just put it out in the sun in open top container for a couple of days. Works real good and costs nothing to run.
