The Pond One Pond Algae Block is useful in preventing the reoccurrence of algae in ponds and water gardens. It is most effective on new ponds or ponds that have been cleaned of existing algae loads. Algae can also be controlled by minimising the amount of feed given to fish, increasing the number of pond plants to a ratio of 3 plants per square mtr of pond surface and increase circulation in the water using a pond pump.
