Fertilizers are not only considered lifeline of vegetation but also for the fish. Several pond owners use fertilizers to increase growth of their fish as well as plants. However, it is an indirect benefit. For example, addition of correct amount and correct type of fertilizer would promote growth of small green plants called phytoplankton. Fish would eat those green plants and their growth would also increase. It has been observed that an ordinary pond yields around 100 pounds of fish per surface acre. However, if it is fertilized, it would yield more than 300 to 400 pounds.
However, how do you know that a pond needs fertilizer? You can use visibility stick to check it. Submerse this stick into the water where its shiny lid is 18 inches below the surface. If it is visible, the pond needs to be fertilized. However, if the lid cannot be seen, it is all right.
If you are going to use pond fertilizer, use around 12-48-8 Pond Perfect Plus around five pounds per acre. It would dissolve in the upper 24 inches of the water. You can pour it through a boat or spray it like a dust from the pond back. You can also use 20-20-5 pond fertilizer around 40 pounds per surface acre of the pond.
Moreover, you must also be aware of the fertilizer type as well as the amount that is to be used per acre.
