This is a good idea in my opinion. And while it uses mosquito dunks which are a huge hazard in natural pond systems, this is not a natural pond system.
Mosquito dunks should not be used in areas that can run off into natural areas particularly if they have water. The BT toxin is incredibly toxic to many other small aquatic invertebrates. Small aquatic invertebrates such as baby dragonfly larvae that are going to ultimately eat mosquitoes. So if you allow this to run off you’ll be ultimately generating mosquitoes. To remove it and refresh it, maybe once a year, the best thing to do would be to pour it down the drain. Septic systems would be fine with this and municipal city water treatment plants would have absolutely no difficulty. I applaud anybody who uses this system instead of any other kind of pesticide.
Best to you all.
