You may be approx. double what is suggested by some. However, if your water is not really used for swimming much and your weed buildup isn't excessive along with fil. algae, then go for it. Just monitor closely.......in the future you may want to gradually reduce your #'s over time...... to be safe? In the mean time enjoy their beauty, character and grace as you enjoy your time on and around the water. Relieving stress is a wonderful thing and if 6 ducks help in that who better to gain from that!!!!!! Best of luck
