Are air stones essential for saltwater tank or are they a freshwater thing?

Hi Sidney,

Air stones are pretty much absent in reef aquaria. You do find them is some skimmers but even there Venturi types have pretty much eliminated them. They are also annoying as they splash saltwater all over and add to salt creep, which is the mysterious ability of salt to appear everywhere but where it is supposed to be. :D

If you have good circulation in your tank the water should have adequate dissolved oxygen levels.
