Dr. Joe, I was referring to bio-balls in a wet/dry, which are only 96 sf/cf according to the source you provided. Obviously, pot scrubbers would provide a higher surface area/volume ratio.

fully submerged dosn't mean no O2.

Interesting twist on UG plates in a seperate tank

fully submerged dosn't mean no O2.

Our atmosphere has 209,000PPM of O2, water, at 80F has 8-10ppm of O2. SOURCE for O2 in our atmosphere
Source for Dissolved oxygen in water

Emersed media gets a lot more O2.

MilitantPotato,

Even confusion runs amuck in my brain...Did you mean what I read or what you said?

The media they use you do not have to clean, Only the floss you have to clean.
And if you notice, they have an area where the water drops into floss than is pushed into the media(so it is getting o2)

.....hummmm this whole japanese setup looks to me more like a coarse sand filter than a wet-dry....

MilitantPotato,

i believe the potato got his facts scrambled....

sounds like lots of O2 in air and very little in water and hence bio media exposed to the atmosphere would have lots more O2... no ???
