Pond chemicals vary from algaecides (kills pond algae), herbicides (kills pond plants and weeds) and many different water chemistry products. Some of these products are for adjusting water pH, improving water clarity, neutralizing chlorine 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'. Both are available in different sizes.
