What about Integrated Pest Management (IPM)....................
I have used alum, tilapia, and algaecides in the same pond. In my experience using only one method rarely works.
As for alum treatments I use them frequently on swim oriented ponds and have had very good results.

What's the difference between a lake and a pond?
If you are selling it's lake!
If you are buying it's a pond!
