The ATB's Bio Pellets are composed of biologically degradable polymers that are best to use with a media reactor. The pellets will allow aerobic growth of bacteria which consequently will consume nitrate and phosphate simultaneously. After about 2-4 weeks, nitrate and phosphate levels should start decreasing.
For larger, or heavily fed aquariums, a higher dosage of biopellets is appropriate. Bio Pellets are consumed by bacteria, therefore additional new pellets should be added every 3-6 months, to compensate for digested pellets. ATB recommends 500ml of BioPellets per 100 gallons of total system water volume.
These lighter and more irregular shaped biopellets are about a third of the size of other biopellets currently on the market, so they tumble more easily within a media reactor.
