16 gallon biocube?

[lilpico]

i got my hands on a biocube this weekend. I was told they thought it was a 29g but when I filled it up and siphoned it out I filled 3x 5gallon buckets and a quarter of another. Also everything I've seen has 3 chambers and this one only has 2. Could this be something other than a biocube?

Thanks

I don't think a bio cube is defined by the gallons or dimensions.

It could still be a bio cube even though it isn't 29 gallons.

I'm not really concerned with the gallons just wondering about the 2 compartments instead of 3 like I see on everything else. And even that doesn't really concern me I just was wondering how it is set up with the filtration
