Graf Calming Inlet Pot

So that the finest dirt particles (<0.35mm) settle on the bottom of the tank, the filtered water is fed into the tank via the Calming Inlet to control the water inflow at the tank bottom. This prevents swirling of the water and oxygen is also introduced to the water at the bottom of the tank. This means the water is always clear and fresh. Used in conjunction with an overflow siphon, this device also prevents mosquitoes by creating a water trap between the inflow pipe and the tank.
