increase oxygen

[stickx911]

I just replaced a powerhead in my system that also pulled in air. Is there anything I need to do to increase the oxygen in the tank? or is regular waterflow enough?

If you have decent water movement and/or a skimmer, there's no need to pull in air via a powerhead. Oxygen is increased via surface / air interaction, not by "pushing" the air into the water, as most people think...

Bubbles inside a tank just create a salt creep nightmare. When those bubbles pop you get tiny amounts of salt spray that goes everywhere.
