Use Ultra Clear Biological Pond Clarifier-Professional Strength for treating small ponds with severe clarity problems or large size ponds that require higher doses of the regular strength Ultra Clear Biological Pond Clarifier. Professional Strength Ultra Clear Biological Pond Clarifier improves water clarity, suppresses aquatic weeds, reduces organic build-up, and removes odor. Professional Strength Ultra Clear Biological Pond Clarifier restores aquatic systems to natural health and beauty. What does Professional Strength Ultra Clear Biological Pond Clarifier consist of? Ultra Clear Biological Pond Clarifier, UltraClear Accelerator and water are combined in a mixing container equipped with an aeration device.

Regular Strength Ultra Clear Biological Pond Clarifier: A liquid, nitrifying bacteria beneficial for improving water quality and the reduction of undesirable suspended solids in the water. It also contains bacteria for the reduction of nitrates and organic waste. It performs nitrification.

Accelerator: A liquid concentrate of bacteria cultures and nutrients. It enhances the degradation of organic residue and denitrification. UltraClear Accelerator restores water clarity and reduces foul odors.

Mixing Container: Can be either a 6-gallon pail or a 55-gallon drum, depending on the volume or the pond to be treated. Requires air pump (as in a large aquarium pump), plastic tubing for delivery of air to the mixing container and air stones for diffusing air into bubbles in the mixture of water, Accelerator & Regular Strength Ultra Clear.

STEP #1: Determine the Volume of the Pond
First, the volume of the pond must be calculated or estimated in order to determine the bacterial dosage for treatment. The dosage for UltraClear Biological Pond Clarifier-Professional Strength is based on the volume of the pond to be treated. The volume is measured in ACRE-FEET.

ACRE-FEET can be computed by first calculating the surface area (in square feet) of the pond. This can be estimated by multiplying the length (in feet) times the width (in feet).

Next, compute the surface acres by dividing the surface area in square feet (computed above), by 42,500. For example, length of 150 feet multiplied times the width of 100 feet equals 15,000 square feet (which is the surface area). The computed surface area of 15,000 square feet is then divided by 42,500 (15,000/42,500), which equal 0.3 surface acres.

Next, compute ACRE-FEET by multiplying surface acres, as computed above, times the average depth of the pond. Example, with an average depth of 6 feet for the above computation, the volume (or ACRE-FEET) would be 6 feet times 0.3 surface acres which equals 1.8 ACRE-FEET.

STEP #2: Determine Dosage for Bacteria
The following table list weekly dosage rates for the pond to be treated. The dosage rate for treatment is based on the ACRE-FEET of the pond as computed above. Determine the dosage for mixing & preparation, based on ACRE-FEET, from the following table:

STEP #3: Mixing & Application
The final step is to prepare the treatment for application. Treatment is weekly. Based on the dosage from the above table, add the specified number of quart bottles or fractions of a quart bottle for both UltraClear Biological Pond Clarifier and UltraClear Accelerator to the mixing container. Fill the container with water after equal parts of both Accelerator have been added.

The appropriate container size (for mixing and aeration) can be determined from the table shown below. It is important that the correct container size is utilized in order to achieve the proper activation.

The mixed, liquid contents of bacteria and water must be aerated for seven full days after mixing. After aeration for seven days, the contents should be poured into the pond to be treated. The procedure should be repeated weekly until the algae clears-up.

The term aeration refers to the process of pumping air into the mixed solution of water and bacteria (Biological Pond Clarifier and Accelerator). The process is achieved with an air pump and a plastic tube with air stones connected to the ends. The air pump discharges air through the tube, which is forced through the porous glass block, which breaks the air into many small bubbles. The stones should be submerged to the bottom of the container when in use.

The aeration process should take place in a room where the temperature is maintained at 70 to 80 degrees Fahrenheit for the entire seven days. A heating element (such as an aquarium type heating element) can be utilized to maintain the temperature in the mixing container if the influent water or room conditions require. Tap water can be used.

Is Professional Strength UltraClear Safe?
The bacteria included in Professional Strength UltraClear are recognized by the Centers for Disease Control and Prevention (CDC) and the American Type Culture Collection (ATCC) as Biosafety Level 1 bacteria. CDC and ATCC give the following definition of Biosafety Level 1 bacteria:

'ATCC cultures and related products are classified by biosafety level (BSL) in an effort to provide guidance to the user on potential risk. The classification is based on assessment of the potential risk using U.S. Public Health Service guidelines, with assistance provided by ATCC scientific advisory committees. Those items in BSL-1 have no known potential to cause disease in humans or animals.'
