Nope it's a new idea that recently come out for nano systems under 7 gallons there has been a lot of banter over this on other forums like nano reef. In essence take a basic Aquaclear put in chaeto on an algae mat in the chamber slow down the water flow by either putting a smaller impellor in or cutting the blades and the chaeto helps act as a skimmer by trapping organic particles and also releasing nutrients back into the system and doing weekly water changes helps control the PH and nitrates. Mind you the larger the system the less effective this becomes hence it is recommended for nano systems smaller than 7 gallons
