    Q
    Will Crystal Blue Black Out clear the pond water that has turned brown due to suspended clay particulates? This was recommended by an AG Agent.
    A

    Crystal Blue Black Out is a pond colorant only, it will not clean or clear pond water. CAL FLO Liquid Limestone is labeled for use in ponds at a rate of 2 1/2 gallons per surface acre of water. If commercial spray equipment is used, add one gallon of CAL FLO to 30 gallons of water and project the dilution on to the water to be treated. If CAL FLO is applied from a boat, slowly pour CAL FLO from a moving boat, letting the motor serve as a mixer.
