Very interesting... maintenance nightmare. Two small fish with a billion plants to suck up nitrates.... distilled water with only essential mineral additives to prevent algae growth. I went to their home site and they are not very descriptive as to its capacity or specs on filtration, heating, and lighting. Cool tank, but overall pretty unrealistic as far as something you can sit back and enjoy goes... I think it would be a constant time-waster for maintenance.
If you could make it work, that'd be sweeeeeet.
Wonder how much they cost???
