I have fed almost every kind of fish food there is and have even experimented at feeding my fish free dog food and can say at this point in my career as a pond boss advocate that you get what you pay for. Right now I am feeding aquamax 600 but have also fed the silvercup salmon food which I think is 45% protein. The silvercup is a little bit more expensive and may be a little bit better but not enough to make a big difference. The biggest difference I saw was when I quit feeding free dog food and cheap catfish food and switched to the aquamax. The fish all of a sudden were really fat and began to really increase in size quickly! The fish will eat dog food and they will eat cheap catfish food but their growth rate is slower and they are not as fat. I have ordered the new sweeny bass feeder and have just ordered some bass food to put in it. I will let you know how that goes as far as growth rate.
