Tips for Pond Maintenance

A few tips for pond maintenance are:

  1. Never add chlorine to the water. It can harm or even kill fish and plants. If your water source is chlorinated, add a chlorine remover or let the water stand in an open barrel or tub for 48 hours and the chlorine will evaporate.
  2. Remove any decaying plant leaves and floating debris. A net to skim the water surface works nicely. Also check the bottom of the pond for debris on a regular basis.
  3. Inspect the filtration system once a month for any clogs or obstructions and clean as needed. Do not clean filter parts with any sort of detergent or disinfectant as this will kill the bacteria for biological filtration. Make sure filtration and circulation pumps are running for 24 hours. Any interruption may cause problems.
  4. Keep the pond well oxygenated by providing good aeration, circulation and filtration. Fast growing plants also help oxygenate the water. If you have a fairly large fish population in relation to the size of the pond, consider adding a secondary biological filter. High quality sponge filters designed for pond use have a large surface area for bacteria that does a superior job. You can also add live bacteria cultures to colonize the new filters that much faster.
  5. Controlling algae is easier if the pond is otherwise properly maintained. Algae eating snails will help, and there has been evidence to show having bales of barley straw in a pond helps to keep algae at bay. As the straw decays, it releases a chemical which retards the growth of algae. There are also various chemical additives for this purpose, but most are copper based and will kill all forms of plants, not just algae.

    Check water levels regularly. Keep water levels consistent, adding fresh water when levels recede. Hot weather and full sun will cause the water to evaporate more quickly and will put stress on your fish.
