Carlos, You could get something like a battery operated toy boat propellor or cocktail stirrer and use that to keep the batch moving. Or do what someone on the list (Ode?) does; is install a small lamp under the vessel to promote water movement. Enhance by putting a funnel in the vessel, wide end over the lamp.
