  2. We advise that you take this opportunity to add more plants to your pond to take up extra nutrients in the pond
  3. A bog filter is a great addition as this will also help to uptake extra nutrients Add beneficial bacteria
  4. Stop feeding your fish until you have an opportunity to catch up on existing algae issues

Pond Megastore Tip! Algaecide should NEVER be used as a long term solution. 
Algae is not harmful to a pond. Some Algae should always be present. A film of algae on the sides and bottom of a pond is natural. You have a pond, not a swimming pool! 

Algae explodes in an algae bloom (either hair algae growing on the sides and rocks OR  the pea soup algae that free floats in water. You probably do not need to test the water. The chemistry is fairly simple for ponds with algae blooms, you have excess nutrients (perhaps decaying leaves and debris in the bottom of the pond, or suddenly you are feeding the fish more than the ornamental plants and filter in the pond can remove.

Algae is very common between season when other plants are waking up slowly, algae grows more rapidly than other plants. Often, during these in between months, algae is actually saving your fish. A heavy load of excess decaying matter in the pond from debris from fish waste, decaying foliage from trees or last years pond plant foliage, may explode ammonia or nitrites into the pond. Never fear, the pond can likely save itself if you don't prevent it from doing so. An algae bloom will soak up these bad, fish toxic items in no time. However, when you visit the pond and see the ugly algae bloom, a home owners first instinct is to get rid of the algae bloom. 

 Adding more plants to your pond is an excellent idea.  Unfortunately, homeowners would  prefer to dump an algae killing solution into the pond. It will kill the algae, but then you still have brownish dead algae in the pond, and these decaying plants I have just covered above, are really bad for fish, so your algae killing solution actually puts fish in danger a short time after being used.

NOTE: If we had enough good biological bacteria and or plants in the pond we would likely not have had the first algae bloom.

Using proper dosages, the algae will die, but it just adds to the dead matter already in the pond. In 3 to 7 days the chemical algaecide dissipates and the algae will likely begin a rapid bloom again. 

Removal of the excess nutrients is key


  • These are  a few methods of removal to break recurring algae:
  1.   10-15% water changes every few days. If using city water be sure new water has a chloramine and chlorine  neutralizer. 
  2.  Proper use of cold microbe-lift water bacteria (IF you have a proper size biological filter)
  3.  Other ornamental plants for uptake of nutrients and partial shade of the water. In cool spring months Hornwort, Water Hawthorne, Golden Club, Marsh Marigold, Bog Bean, Louisiana Iris and Blue Flag Iris all do well for early spring nutrient uptake. 
  4.  Mechanical filtration is also good with the use of sand filters or other mechanical methods. 
  5. Stop feeding fish. Koi and goldfish thrive on algae, there is no need for food when algae is present. We feed fish  because we enjoy it and fish food companies want us to. In almost thirty years of watching koi and goldfish in  ponds I have never seen any starve to death. Perhaps in overstocked koi ponds with no plants-- that is possible, but most  homeowners have plenty of food in the pond every day of the year to keep fish sustained.

Microbe-Lift PL, HC, AUtumn Prep, and Spring & Summer all contain photosynthetic bacteria that helps to eliminate many types of algae in your pond and is 100% safe for use with fish and plants.
