but wouldnt that introduce air bubbles to the tank??

They don't exactly create 'flow' but they do stir the water and create movement. My predicament is that i have a cylinder tank and nowhere to really install a powerhead. Are there any other disadvantages to having an airstone in a saltwater tank?

Could possibly introduce microbubbles, also makes salt creep like mad. Could you maybe try a hydor koralia? I think the magnet feture would enable you to put it on a cylindrical tank.

i never asked when i was told about not putting an airstone in a marine tank i guess thats because i was just trying to get the basics at the time i need to know what exactly makes micro bubbles bad anyway?

If you don't have some kind of surface water removal (to a sump), then an airstone in the tank will turn your tank into a full size protein skimmer. You'll have a good scum on the surface.

When I had my hex tank, I ran the return pump from the sump into a SQWD which split into two opposing outlets in the hex. Every 30 seconds or so, the current would change from clockwise to counterclockwise.

So you're saying a airstone in a cylinder tank isn't a bad idea?

I think he is joking with you. Using an airstine is not going to help with flow in your tank. There has to be a rock that you can hide a PH behind or hang one up high pointing downwards.
