cat asked: My lily pond is a fiberglass insert. It is 8 ft. long, irregularly shaped, 18 inches deep and holds approximately 300 gallons of water. It is located within my atrium which is surrounded by four outside walls so the option of running a hose from the pond, down hill, is out of the question. Is there some device or equipment that I might use to empty this pond for the purpose of cleaning it. Until now I have had to empty it bucket by bucked and using a dry vac to get the last bit. Of course moving a dry vac with a tank full of water is quite difficult. Are there any suggestions? Please, and thanks.
