while I highly doubt that this product has what it takes to make a fishtank maintainence free I do believe that it is posible. A very large dinitrification chamber inline with A highly overpowered skimmer and a large fluidised bed filter could do it if you had algea eating fish and inverts which are in abundance in salt water. you could even automate moveing the foam from the skimmer colectioncup to another location ondry it out creating a hard pelet of nasty icky foam junk. but if you had this set up you could certainly put a bit more time into the presentation than they did. IMO
