Mike,
How big is your pond, and why only 3 LM? Do you have other predators? What is/are your management goal(s)?
I switched to Optimal from a cheap grain based feed for a couple of reasons, better growth to hopefully get the bg spawning earlier and better water quality. I have had FA problems in the past and used a multi prong approach, but I believe the fish meal based feed was part of the solution.
