Houston, there is merit in what you are saying. Any way you slice it, they want you to pay a lot for supplemental microbes. With good bottom aeration, natural bacteria will develop very rapidly, but we Americans are always looking for instant gratification and thus will pay a premium for it.
Our point is that the brewing process, including injection of air at optimum temps. will multiply the counts very rapidly, doubling in 20-30 minutes. That is the key. Then of course good aeration.
One post under aquatic vegetation, vaguely pointed to increased weed growth after using aeration for 3 wks, when the idea is to totally change the dynamics of the pond, but not overnight. I am very sure that any of the many formulas and methods of getting microbes to work will help aaccomplish that. We are all looking for some positive feedback from your pond. Good luck with it.
