|                         Sunlight encourages photosynthesis
                        in your pond water. As a result,
                        Algae, the first form of pond life, 
                        grows rapidly, turning the water
                        green and murky. However, in nature
                        there is always something ready to
                        consume plant or vegetable matter,
                        and in this case that something is
                        naturally-encouraged bacteria. The
                        pump draws the algae-contaminated
                        water down through the pea gravel
                        into the ‘legs’ of the Spider.
                         In the process, the algae is force fed
                          to the bacteria. Furthermore, the
                          bacteria will naturally develop in
                          numbers to balance the ‘food’
                          supply. The filter's highly effective
                          natural cleaning cycle is kept alive
                          by the continual circulation of pond
                          water from the pump. |
