Southern Excellence Self-Dispensing pond fertilizer provides food to microscopic algae plants. Algae is eaten by tiny animals as well as insects which become food for small fish. The small fish, in turn, become food for larger fish forming a continuous and balanced food chain. Fertilization helps reduce and control aquatic weed problems as well by creating a shaded pond bottom not suitable for weeds to live and grow. A properly fertilized pond using Southern Excellence can increase fish yield by 400%. Suspended at the surface, Southern Excellence Self-Dispensing pond fertilizer mixes with the upper 3-4 feet of water where algae and oxygen are most plentiful. This method does not waste fertilizer or cause problems on the bottom of your pond. To use, simply extend the anchor and cord to full length, and place into 4' to 6' of water. One bucket will fertilize a pond size of up to 5 acres per month. For maximum fish production, maintain a green color from spring to fall. Use a secchi disc to check color at 18" - 24". Simply extend anchor and toss. Southern Excellence fertilizer is a superior product because of its high analysis and it being suspended at the surface allowing it to dissolve and mix with the upper 3 to 4 feet of water where algae and oxygen are most plentiful.
