The Aerator is used to oxygenate the water / nutrient solution. The air tube has to be inserted on the top protrusion and can be made leak proof using the 3Dponics Air Lock. Coins are inserted into the slots provided so that the Aerator can rest at the bottom of the nutrient container, immersed in the water / nutrient solution. Know how to make this part better?
