I feel so bad about the frogs in our pond. I think we killed them!
We moved into this house with a pond and waterfall. When we moved in the frogs were deafening in their cacophony each night. We just loved it.
But we have a problem. We have never had a pond in our yard, and after a few weeks we noticed algae growing in a big way.
Light bulb! Maybe that was what that little bag of giant tablets was all about that was left just inside the front door when we moved in! On the bag was a stamp with the name of the pond company. I called, and they said I needed to put one of those giant tablets in the pond where the water runs, and to replace it when it's gone. I asked him about the wildlife using the pond and he assured me it was safe. After all, we drink water with chlorine. Well...
My instincts said it was not good, but I did what he told me to do and now I don't hear the frogs anymore. :-(
I went online and it said they are very sensitive to chemicals. But what I don't understand is why the owners would leave these tablets where we would see them if it might hurt the frogs. They obviously loved the frogs, too, due to numerous frog statues throughout the yard. Geeze, a note on how to care for the pond would have been helpful!
Now I just feel sad.
