Do I need a bubbler to oxygenate the water if I have a double sponge filter

[DaPrawf]

My old HOB filter died and I ordered a double sponge filter to replace it. I'm wondering whether the sponge filter will generate enough water movement to oxygenate the water or whether I need to supplement it with a separate bubbler.

(I'm running an undersized regular sponge filter as a stopgap until the new arrives.)

 

Thanks.

You can certainly increase the airflow on one of these to provide plenty of surface agitation.  I dont think you would need an additional bubbler for oxygenation, butit can be added to help with flow in a spot of not much circulation.

And if I am putting an air bubbler or stone, I like having it do double duty in providing filtration as well…

 

I am fond of those double sponge filters above and have a few.

you probably wont need an air stone in addition to the sponge filter, but you can always add one if you feel the need.

From my understanding, a single bubble source like you use to power a sponge filter like that *should* bring your O2/CO2 levels to be on par with atmospheric levels pretty well, so an extra might help with circulation if placed in another part of the tank, one should do a good job of keeping the gas levels where they should be in your water.
