Measure Biopellets
Add one cup (236mL) of BRS Biopellets per 50 gallons of system water volume to the reactor. For example a 100 gallon tank would use 2 cups of BRS Biopellets.
Place Reactor & Pump and Adjust Flow
Place the reactor and pump in the tank and adjust the flow so that all of the media is tumbling. Faster tumbling will keep the media free of biofilm and make it easier to keep the media tumbling for prolonged periods of time.
Add Beneficial Bacteria Strain (optional)
Add a beneficial bacteria strain like KZ Zeobak directly into the reactor. This may speed up the process and help maintain populations of beneficial bacteria but is not absolutely required.
Wait 4-8 Weeks
Wait 4-8 weeks for the bacteria to populate. During this time resist any temptation to change anything even if nitrate levels are continuing to rise. Some aquarists experience a bacterial bloom when first starting this system which clouds the tank for a few days. The cloudy water is generally scarier than harmful, but it can reduce the oxygen levels in the tank. If you do experience a bacterial bloom we recommend aiming a few powerheads at the surface of the water to maximize gas exchange.
Continue water changes as usual.
Future Maintenance
Depending on the system add new Biopellets every 6-12 months. Do not remove remaining biopellets
