I feed 2 ponds daily. I have never paid tax on Optimal shipped to me. If you want different pellet sizes of Optimal. I mixed optimal jr. and optimal blue gill for at least 1 year to 18 months. Then go with Optimal Bluegill. In my opinion fish grow much faster on Optimal. It is the best food I have used and the owner is great guy and not a large corporation.
