increasing O2 levels

[digitalsteve]

whats the easiest way to increase o2 levels without crazy microbubbles

adding a powerhead or closed loop isnt an option (long story) , what about adding a split opening lockline in order to direct the return flow in two different directions thus adding more oxygen around various areas.

any tips or suggestions i would appreciate.

Do you have a skimmer?That will do the trick.

i do have a skimmer.... when i filter out the microbubbles o2 levels seem to drop considerably

doubt itll work but have u considered just adding o2 into the tank directly?

[digitalsteve]

from like an o2 tank?

im gonna try and run a long line out to a window to try and bring some fresh air in

do you have any movement at the surface of the water? If not try that, it will help with gas exchange at the surface.
