I like my 14 Biocube.....I wanna go to a 29 as soon as I can afford it.

I top off less than once a week. I try not to let it get so low that it starts spitting bubbles. If it gets any more than an inch or so below the "full" mark, then I top it off.

I built this little guy on 2-19-2007. You can check out the process HERE.

Here it is.....
