how many gallon/ton water does one dunk covers for pond?

I realize this is an old question but for people wondering, we have an 86' diameter pond. To find out how many dunks are needed we half the diameter to the radius (43), square that number by multiplying it by itself (43x43=1849) then multiply by 3.14159 (5808.8) now divide by the 100 Sq Ft each dunk covers = 58 dunks to do our pond for 30 days. Wow. The better solution for a large pond is a submersible sump pump on a timer to come on at regular intervals and keep the water aerated and moving.

What is the exact definition regarding cats and dogs safety? What agency states the safety of the product?

Here is a bit more info with OSHA's required MSDS. I think the EPA designations are most useful in answering you pet related questions.Material Safety Data SheetProduct Identity (Label Name): Mosquito DunksSection 1Manufacturer's Name: Summit Chemical Company7657 Canton Center DriveBaltimore, MD 21224Telephone Number: (410) 282-5200 / (800) 227-8664Date Prepared: 11/01/98EPA No.: 6218-47Section 2 Hazardous Ingredients/Identity InformationHazardous Components OSHA PEL ACGIH TLV Other LimitsNo hazardous or toxic componentsSection 3 Physical CharacteristicsBoiling Point: N/AMelting Point: NoneSpecific Gravity: Less dense than waterEvaporation Rate: N/AVapor Pressure: N/AVapor Density: N/ASolubility in Water: N/AAppearance: Light brown donut - Shaped disks.Odor: Essentially noneSection 4 Fire and Explosion Hazard DataFlash Point: NoneMethod Used:Flammable Limits:L.E.L.: NoneU.E.L.: NoneExtinguishing Media: Water, conventional fire extinguishersSpecial Fire Fighting Procedures: NoneUnusual Fire and Explosion Hazards: NoneSection 5 Reactivity DataStability: Stable: X Unstable:Conditions to Avoid: Protect briquettes from moisture during storageIncompatibility (Materials to Avoid): Alkaline conditions above pH 9 may denatureproductsHazardous Decomposition Products: NoneHazardous Polymerization: Will not occurConditions to Avoid: NoneSection 6 Health Hazard DataRoute of Entry:Inhalation: NoSkin: NoIngestion: NoHealth Hazards (Acute and Chronic): None knownCarcinogenicity:NTP: NoIARC Monograph: NoOSHA Regulated: NoSigns and Symptoms of Exposure: No exposure hazardMedical Conditions Generally Aggravated by Exposure: None knownEmergency and First Aid Procedures: None requiredSection 7 Precautions for Safe Handling and UseSteps to Be Taken in Case Material is Released or Spilled: Clean up with soap and water.Waste Disposal Method: Conventional trash removaland land fill disposal.Precautions to be Taken in Handling and Storage: Store in a cool dry placeOther Precautions: Reseal opened containers afterpartial use.Section 8 Control MeasureRespiratory Protection (Specify Type): None neededVentilation:Local Exhaust: None neededMechanical: None neededSpecial:Other:Protective Clothing: None needed, wear normal work clothesGloves: None neededEye Protection: None neededClothes: None neededProtective Clothing: No special practices neededCheers.
