"String" Algae

  If you have large amounts of string algae in your pond, such as shown,
it is best to remove it by hand prior to treating your pond.

How to measure the gallonage of your pond



Pond Balance

Pond Balance (Imported from the U.K.)

This product makes key micro-nutrients unavailable to string algae. Pond Balance loosens string algae for easy removal by hand or filtration.

This product is harmless to animals and all vascular plants such as lilies and marginal plants when properly dosed. Please note the treatment amounts below are total package treatment amounts.

Often it is the case that you will not begin to see results until the 3rd dose (3 weeks). At this time the string algae will begin sloughing off from the surface of the pond. Extra servicing of your filter is likely during this time.

A single dose usually will not achieve desired results:
  Use once a week for 4 weeks, then once or twice per month thereafter, i.e., S726 is a 6-week supply for a 1500 gallon pond.

As an alternative to the once or twice per month dosing of pond with Pond Balance - maintain with Barley Straw.

TIP Each box or tub of Pond Balance comes with a blue measuring scoop. Typically, on the largest size of Pond Balance (S727), that scoop will be buried in the product, making it difficult to find. The dosage is 2/3 of a Tablespoon per 75 to 90 gallons of pond water. If you have a bad case of string algae, dose it at 2/3 Tablespoon of Pond Balance for 75 gallons of pond water. If you have a moderate to light string algae problem, base your dosage on 2/3 Tablespoon of Pond Balance to 90 gallons of pond water.

This picture shows an example of a pond which once had 6" long string algae. The surface dwelling algae on the fiberglass liner in the upper right hand corner of the picture is the desired growth level. Your pond liner should have a dark forest green fuzzy velvet appearance. This is the sign of a balanced pond.

Do not remove surface dwelling algae from your pond. Surface dwelling algae (the right species) is beneficial to your pond and over time actually becomes a part of the "filtering" system of your pond. The beneficial algae function as a high surface area for beneficial aerobic nitrifying bacteria to cultivate. These algae also utilize nitrogen waste as a nutrient source. The older your pond becomes, the more mature this process becomes.
