No doubt the aqua max and similar products are best but I have been feeding 32 % catfish floating for years and my blue gill are big and fat. I run 4 feeders on 2 ponds I own so 23 dollars a bag is ok for the 32 percent. Nearly 50 dollars for the aqua max and others these days is higher than I am willing to go. I guess there is best and then good enough. I go with good enough for now
