Good comments but in simple terms they harvested the same ponds twice within 6 months as the other ponds have failed thinking that a few extra baffles would increase precipitation of the salts from a weaker diluted brine and give more harvested salts volume to tweet about ! Politly putting they tried to pull the wool over us and have been caught well and truly out because they couldnt make it work IMHO
