Pond Chemicals

Our pond chemicals and pond treatment products include:  algaecides (kills pond algae), herbicides (kills pond plants and weeds) and many different water chemistry products, pond dyes, pond chemical surfactants (makes the chemicals stick to the pond weeds better instead of being washed off).  Some of these pond chemicals are for adjusting water pH, improving water clarity, neutralizing chlorine, coloring the pond water so less sun gets filtered through, and many other uses.  Some chemicals are restricted in various states so be sure to find out what products are restricted in your area.  Be sure to check our 'How To' Guide to view the list of recommended treatments for various pond weed applications and their restrictions. 

If you're looking for something to reduce the algae naturally, check out our Beneficial Pond Bacteria such as Microbe Lift for small ponds less than 250 square feet or PlanktoniX for larger ponds and lakes.  Both are natural products and not considered a 'chemical' and are available in different sizes.

Remember:  Pond algae and pond weeds grow because there's excessive nutrients and sunlight in the water.  Nutrients are from sludge, muck, fallen leaves, etc.  When you get at the root of the problem and decompose or remove these nutrients, your pond algae will become less of a problem.  Using a lot of pond chemicals are not good for your pond as they are always altering your water chemistry and the dead algae and pond weeds on the bottom of the pond add to the nutrients that are already there which is feeding your unwanted algae and pond weeds and causing them to grow.  As with most things in life - get at the root of the problem.  For this case, reduce the nutrients by adding PlanktoniX pond cleaning bacteria (available in several sizes) which is completely safe and very effective at getting rid of unwanted wastes, sludge and muck, etc.
