nope, it is only 1g. the pic and scape just make it look bigger.
i am well aware of the total volume theory oldman, and have it all taken care of. thanks for the concern though.
there are a lot of misconceptions about sticking levels, and the "needed" amount of swimming space. not to mention the idea of certain fish needing to be in certain group sizes.
but as the entire concept of fish keeping is completely man made, none of these ideas are truely relevant.
WP are perfect.
bio-media surface area is ridiculously overkilled. (while majority of the bio media is not being used, it does help to stabilize the system with any rise of ammonia, and the filter cn be moved to a much larger display with no changes in the filter itself, so it works out in the end. i like to think long term)
total area of available swimming space is sufficient for the inhabitants.
and in the end, it is not a permanent set up. when i deliver the tank to my friend, i will also be setting up a 10g display for this filter, so the inhabitants can be moved over, and the 1g used for something else.
