Eheim dual feeder feeds to much? What food you using?

Do you have an overflow? I find when feeding small pellets they just sit on the surface and eventually go down the drain. Which is why I never bothered with an auto feeder.
I usually soak them in a cup then use a baster to put them under water.
That being said... my tank is a 40 breeder so it doesn't take long to get to the overflow.
