Today I was watering bonsai trees in my bonsai hospital (where my last Japanese maple tree already probably succumbed to the heatwave). I am using the water from the pond at the end of my sewage cleaning facility for that. And this is the sight that greeted me today.
Every day when I come there I hear several splashes as the frogs sitting around the edges of the pool jump into the water when I disturb them. Today I got lucky and this one was just chilling in the water and did not scamper until I plunged my watering can into the water.
I take this as a sign that my sewage cleaning facility works well, despite the official tests coming just on the edge with regard to ammonia content. I haven’t seen any tadpoles, unfortunately, but I do have happy frogs every year, plenty of dragonfly larvae and water beetles, an occasional water mollusk, and as you can see, the water is so clear that one can see right down to the bottom of the pond. It will get a bit worse in the fall when the trees shed leaves, especially the walnut tree, but that has nothing to do with the sewage cleaning efficacy.
