Jason, if it is affordable, feed as much as they will eat in 15 minutes at each feeding. Of course this also depends on the actual population of your fish, but I feed up to 10 lbs per day per feeder on an 8 acre lake. The feeding times you picked are good - early morning, late afternoon, and then once or twice during middle of the day seems to work. I use the Purina game chow but I am sure Aquamax is also good. The feeding program makes a huge difference over time. -15
