Do you have a Dissolved Oxygen (DO) profile for the four seasons? What depth is the thermo-cline at each season? If the thermocline is at 10 feet most of the year, place most of them in 10 feet or shallower water. If eight, place most in eight feet deep water or less. If you have a bottom aeration system or no thermocline at all, place in all depths. It also depends on the fish you have? Bream and bass will tend to use shallower water areas if structure is present than catfish that tend to use the deeper structure.
We have designed an attractor for our clients that is easy to make and cheap ($60 each) to build yourself. We make them six feet tall, but you can make them any height you want.
