IDEA : Japanese Style Filtration...

[Cichlas]

what am i thinking of that turns nitrates into nitrogen gas?

anaerobic bacteria

Would this be the same type of beneficial bacteria that is in my canisters ceramic rings, which is different than the stuff in my wet/dry?
Is one better than the other?
Is it best to have both types?
does it matter?

In a very limited amount (if you believe the advertising).

No, they are completely different (so to speak).

Yes.

Yes.

There are several threads on this in here so I won't repeat things.

that's a lot of media...

does look like they have ugf and just open the pipe to clean.

so do they ever clean it???

My guess is that the reduced amount of square footage in most Japanese homes compared to U.S. homes is the reason for this design. The use of ceramic media gives a greater surface area to volume ratio and takes up less room than the comparatively bulky plastic bio-balls. Thus, it's a trade off between the higher efficiency but space consuming wet-dry for greater biomedia surface area. Plus, I'm sure it's more quiet than a wet/dry and, therefore, more suitable for use in close quarters.

Didn't look like there was to much space saving going on there. The wet dry for my 300 is half the size of those monsters... if not smaller. I have seen a few of the type sumps popping up around here. Kinda reminds me of a saltwater sump with a filter media instead of live rock.

But the surface area is likely higher than a comparably sized wet/dry would provide.

I gotta challenge that...scrubbies have 370 cu.ft. of surface area per.

typo ?? 370 sq ft per cubic foot ???

most of my sump media is fully submerged too, similar to the pics shown.
