submersible pump and air pump

[Calvin]

Hey there, I have a problem and I was hoping you guys and gals can help me. You see...I just
brought an submersible pump and an air head pump from a garage sale. Both of them are made from
Wave Castle and I can't figure out how to use them ( & what's their purpose).Both of them works
but it's doesn't seem to pump any water or do anything thanks in advance Calvin
