Poor clarity, aquatic weeds, organic sediment, and foul odors detract from a pond's natural beauty. Fertilizer run-off, fish and wildlife droppings, and dead leaves and grass clippings contribute to these problems. UltraClear Biological Pond Clarifier improves clarity, cleans the water, reduces organic build-up, and removes odors. UltraClear Biological Pond Clarifier restores aquatic systems to natural health and beauty.

UltraClear is the environmentally friendly way to beautify your ponds and fountains. UltraClear works naturally and actually benefits the environment. UltraClear Biological Pond Clarifier is 100% safe for fish, wildlife, and turf. UltraClear Biological Pond clarifier will not harm fish or other wildlife that are in your pond or use your pond. And, UltraClear Biological Pond Clarifier is easy to use. Simply shake well and pour straight from the bottle according to the dosage instructions.

What Are the Main Applications of Biological Pond Clarifier?

There are three main applications:

Spring Prep

General Pond Maintenance

Treating Problem Ponds

During Spring Prep (pond start-up), the main objective is to rapidly establish a healthy population of bacteria to 'cycle' the pond. Fish excrete ammonia, which can be toxic at very low levels. When bacteria cycle, it means they successfully oxidize ammonia (NH3) to nitrite (NO2), then to relatively non-toxic nitrate (NO3). Other bacteria can then convert nitrate into nitrogen gas in a process called denitrification. Use of Biological Pond Clarifier for Spring Prep prevents build-up of toxic ammonia and nitrite, making your pond a healthy place for fish.

As the summer proceeds, Biological Pond Clarifier serves its main function: maintaining your pond's beauty and clarity. This is probably the most common and important use of the product. Following the Maintenance program will prevent most common pond problems from occurring.

Finally, Biological Pond Clarifier can be used to solve most pond problems. Even when a problem already exists (poor clarity, odors, etc.) regular strength Biological Pond Clarifier.


What are the main benefits of using UltraClear Biological Pond Clarifier?


UltraClear Biological Pond Clarifier improves removes toxic ammonia and nitrite, improves water clarity and purity, and helps to reduce organic sediment (Note: when a pond receives significant organic influx, such as leaves, clippings, animal fecal waste, etc., use UltraClear Sludge Digester along with Biological Pond Clarifier). The net result of the use of UltraClear is a clear, beautiful, and naturally healthy pond.


How does Ultra Clear Biological Pond Clarifier work?


UltraClear Biological Pond Clarifier consists of 100% natural, completely safe, soil bacteria. The bacteria in Biological Pond Clarifier consist of two main classes, chemolithotrophic and heterotrophic.


The first class, called nitrifying bacteria, oxidize ammonia (NH3) to nitrite (NO2), then to nitrate (NO3). These bacteria also consume large amounts of phosphate. These bacteria are chemolithotrophic. This class of bacteria requires an aerobic zone (meaning a zone with sufficient dissolved oxygen).


The second class of bacteria in UltraClear Biological Pond Clarifier digest organic sediment and dissolved organic carbon. Plus, these bacteria convert nitrate into completely non-toxic nitrogen gas. These bacteria are heterotrophic. This class of bacteria is also facultative, meaning that they function in an aerobic or anaerobic zone. This is important since many ponds have anaerobic zones where organic sludge builds-up and the dissolved oxygen level is no significant. By converting ammonia to nitrite then nitrate, converting nitrate to nitrogen gas, and rapidly consuming phosphate, UltraClear Biological Pond Clarifier reduces specific sources of nutrients that promote undesirable clarity problems.

  • Essential for spring preparation.
  • Ideal for pond start-up.
  • Treats pond clarity.

Dosage: Use one ounce weekly per 2500 gallons. See product label for more details. 


Example: Assume a pond of average LENGTH=22 FT., average WIDTH=16 ft., and average DEPTH=3 ft. The volume of the pond is 22 x 16 x 3 =1,056 cubic feet.
