I avoid the 'bits' getting into the tank by activating the powder in an old carafe first. 900 GPH clears up the cloudiness within minutes. I dissolve 4 tablespoons of Rid-X in aquarium water and shake/mix the concoction about every 30 minutes for 4-6 hours. Afterwards, I pour the liquid portion into the tank while leaving the sediment at the bottom of the carafe. A little bit of the sediment may get in the tank but doesn't seem to adversely affect the fish. The filter takes care of the sediment fairly quickly.
