We just went out to check our chlorine levels and our filter and found all over the white metal poles these tiny swarming bugs that are smaller than a grain of rice and kind of a light brown/tan color. Upon reading a few posts in this forum, I think they are something called springtails. Apparently they come out after a rain as they love moisture, and we had heavy rains yesterday (at least 3 inches). Do you know anything about these icky bugs?
