Tj, in my pond I feed approx. 50# per month, and there's some left floating after 15 min. (AM600). I have a client with a .7 ac pond with aeration (LMB/BG) that feeds 100#/month and he could feed more as it's all gone by about the 10 minute mark. George, I agree, that 15 minute rule is VERY arbitrary. But, I don't know any other way to explain it.
