To adjust the chlorine feed rate on the R171016 Pentair Rainbow 300, first turn off the pool or spa pump. Then, loosen the adjustment ring and move it up or down to increase or decrease the amount of chlorine being dispensed. Finally, tighten the adjustment ring and restart the pump to allow the feeder to distribute the adjusted amount of chlorine. It is important to regularly check and adjust the feed rate to maintain optimal water chemistry.
