November 25, 2006. Much as we enjoy the sound of the water rushing down the waterfall and the twinkle of the underwater lights, we've turned the pump and lights off for the winter. The river of rocks looks forlorn, but the other pump, moving water from the main pond into the bog filter, is still running, so there's still some water movement. The water is crystal clear, which makes it real easy to see all the string algae swaying about. |
