Biological pond filters combine with beneficial bacteria to keep a garden pond healthy and clear. These filters remove debris, algae and dirt and allow beneficial bacteria to thrive in the pond. External biological filters are usually better than submerged ones. If there is room, an external filter such as a waterfall filter can be installed. If there is not enough room, a submerged biological filter with added bio-media like ceramic rock or bio-balls can be installed. Although many people buy UV filters, UV can kill bacteria as well as algae which defeats the purpose of a biological filter. Biological bead filters are filled with thousand of tiny poly-beads that provide a larger surface area for beneficial bacteria to grow. Bead filters are generally able to clear water more efficiently than other biological filters. Biological filters are required if there are fish in a garden pond. It should not be cleaned very often but on the occasions when it needs to be cleaned, this should be done with tap water and not chlorine as this kills bacteria. More terms explained
Maintain the water level in your pond such that they stay in the right limits both in summer and rainy seasons.
Replace pond water in periodical intervals for safety and good health of aquatic life. Clean filter system every so often to keep away clogs and obstructions affecting the water flow. Remove the decayed plants from pond bottom to keep up safety of aquatic lives. Add minimal dechlorinator to lessen chlorination effect in fresh water. Offer proper aeration to the plants to keep up freshness of water, taking care of the aquatic plants with proper fertilizers.
To keep your ponds clean add some helpful bacteria and natural cleaning agents that feed on fish wastes. They help convert ammonia to nitrites further to nitrates that acts as a natural pond filtrating agents. They are absorbed by the aquatic plants to produce oxygen thus forming a nitrogen cycle. This action reduces the phosphorous and organic waste content in pond avoiding algae formation. Pond maintenance may sound to be simple but it requires continuous care to be taken keeping a balance over healthy ecosystems and clean water preventing algae.
