I took coffee and a stone book , and a list of rocks to do a bit of research , and enjoyed myself . The pond pump started slowing down , and I watched it slow in the few hours I was out reading , so I cleaned it . The algae are floating around the pond thickly , and it had clogged the pump again .

Question: Why might I be pumping the water from the pond ?
Answer: I might be trying to add the excess water .I might be trying to add the excess algae .I might be trying to remove the excess algae .None of the above choices .
