Abstract: A jet system is beneficial in keeping a drilling particulates of a drilling fluid evenly mixed within an upright storage tank having a side wall, a top wall and a bottom wall. The jet system has a nozzle on each half section of a horizontally disposed upper arm and a plurality of nozzles on each half section of a lower rotatable arm disposed adjacent the bottom wall for keeping particulates of the drilling fluid suspended above the upper and lower arm. The upper arm redistributes and suspends particulates of the drilling fluid from near the bottom of the tank above the upper arm to thereby keep particulates of the drilling fluid suspended throughout the entire volume.
