About Pondh2o basket shop


PondH2o String Algae Pond Water Treatment contains beneficial pond bacteria. Simply throw sachet into the pond, the bacteria will help to reduce string algae and blanket weed. Toss into the pond ideally near moving water or into a pond filter chamber. The bacteria helps to reduce excess fish food, fish wastes, pond much, toxic nutrients such as ammonia and nitrite, problem causing nutrients such as nitrate & phosphate, and reduce bottom sludge & odors.

Used as an alternative to chemical and mechanical treatments, blanket weed treatment for ponds is not just good for the environment, but prevents drain blockage and lack of oxygen caused by the spread of algae and blanket weed.

Made in the USA and effective. Best used when water is above 50 Fahrenheit. Circulate and aerate the water in the pond. Easy to use.


  • Apply 1  1 oz sachet per 1000 gallons of water
  • Apply every 1-2 weeks, or as needed to keep your water clean & healthy!

Each 1000 gallon water soluble String Algae Pond Water Treatment sachet dissolves in the pond water leaving no mess and can not be overdosed. Safe for all aquatic life.  Remove algae with our string algae brush HERE.
