Creating flow

[likwid]

Don't use an airstone unless you want tons of salt creep.

Wait a minute you say an airstone can be used in marine as well?

I use airstones in my top off resivour to help maintain PH and keep the water fresh.

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?
