LSPWT Savings ChartLS-PWT2®-livestock water treatment contains the strongest animal feed grade mineral acid available. A much lower additional rate is required to acidify drinking water to biologically effective low pH levels. This lower addition rate provides pH reduction with no bitter taste. Birds and livestock won’t back off from LS-PWTtreated water, so optimum water consumption is maintained.

Plus, since LS-PWT2 a pH water treatment is available in bulk, it provides substantial cost savings.

LS-PWT2 Product Chemistry

When LS-PWT2 is applied it breaks down into sodium, hydrogen and sulfate.

NaHSO–4 >  Na+  +  H+  +  SO–4

The hydrogen lowers pH. LS-PWT2 is a safe mineral acid that breaks down into products naturally found in the environment.

Environmental Chemistry

LS-PWT2 meets the guidelines of a green ingredient. It is:

  • Biodegradable
  • Non-toxic
  • Ozone friendly

LS-PWTfollows the principles of Green Chemistry as described by the EPA and the California Department of Toxic Substances Control:

  • The production process generates no waste and uses no solvents
  • The process is analyzed in real time to prevent pollution and maximizes “atom economy” by containing all of the starting materials in the final products
  • It is designed to be fully effective and has little toxicity
  • It degrades after use breaking down into innocuous substances
  • It is designed to minimize the potential for accidents including explosions, fires, and releases to the environment.


Alkalinity is the buffering capacity of water. It measures the ability of water to neutralize acids thereby maintaining a stable pH. Alkalinity of water consists of bicarbonates, carbonates, and hydroxides, which combine with H+ ions to neutralize them. High alkalinity water requires more acid to reduce the pH.

How do I decide what rate to use?

Two factors determine how much LS-PWT2® is needed on a given farm: end-use of LS-PWT2® (crop acidification or chlorine management) and characteristics of the water source (pH and alkalinity). Refer to the rate chart for the appropriate amount in each situation.


How much LS-PWT2 is too much?

The pH of the drinking water should not go below a pH of 3.0.

Is alkalinity important when testing water?

Yes. Alkalinity is a measure of the carbonates in a water source that will bind to the LS-PWT2® or any water acidifier. Only after all of the carbonates in the water are bound by the LS-PWT2® will the pH begin to drop. The higher the alkalinity of a water source, the more LS-PWT2® or any other acid will be needed to reach the target pH.

What is the difference between LS-PWT2 and citric acid or vinegar?

LS-PWT2® is a strong, mineral acid while citric acid and vinegar are weak organic acids. LS-PWT2® has a low addition rate and a pleasing taste to birds while organic acids such as citric acid taste bitter causing birds to reduce water consumption.

How long should I run LS-PWT2?

LS-PWT2® should be run for the first 7-10 days the birds are placed in the house, around feed changes, and prior to processing. More information about usage for different types of birds can be found here.

What is pH?

pH is the measure of the number of hydrogen ions in solution. The more hydrogen ions in a solution, the lower the pH will be.

Will birds drink water at a low pH of 3.5?

Yes, if it is acidified with a mineral acid such as LS-PWT2®. Because mineral acids easily donate hydrogen ions into a solution, they have a low addition rate and a pleasing taste to birds.

I have never run LS-PWT2 before. Is it ok to run it mid-flock?

If you have never used LS-PWT2® before, it is recommended to use it for the first time while the house is empty. Because LS-PWT2® cleans the water lines so thoroughly, dislodging lots of biofilm and residual material in the lines, a high pressure flush is needed to remove that debris from the water lines. Using LS-PWT2® with birds in the house for the first time will make it difficult to remove all of the debris dislodged by the cleaning process possibly causing clogged nipples and birds to ingest the dirty material.

How do I properly test water to determine addition rate of LS-PWT2?

A sample of the water can be taken either at the well or at the entrance to the house. A pool test kit or test strips can be used to determine the pH and alkalinity of the water source. Once that is known, use the chart below to determine addition rate.


Do I need to make fresh solution everyday?

No. Unlike antibiotics and other water additives, LS-PWT2® is very stable when mixed. A stock solution of LS-PWT2® will maintain its potency for at least 30 days.

Does LS-PWT2 help bird performance?

Yes. By acidifying the crop, LS-PWT2® helps the bird in digestion and the maintenance of healthy gut microflora.

How does crop acidification work?

Many have experienced success with water acidification programs that are properly designed to deliver the right pH at the right times.. But given that water acidification doesn’t seem to change the pH in the intestines, how does it work? The answer seems to lie in the difference between the original pattern of gut movement and digestion in birds and the altered pattern on modern commercial diets. There are several areas in a bird’s gut where movement is actually a two-way street. When a bird was eating whole grain and bugs, the meal would go from the proventriculus to the gizzard for grinding. Then the gizzard would send the meal backwards to the proventriculus for another acid bath. This might happen 5 or 6 times until the meal was ground finely enough to move on to the intestines. In a commercial mash or pelleted diet, this back and forth movement between the gizzard and the proventriculus is dramatically reduced so there is very little acid contact time of the meal in the proventriculus. With a diet that includes whole grains this back and forth movement is frequently repeated before the meal is allowed to enter the intestine increasing acid contact time many fold. The most plausible explanation for the efficacy of acidifying water below a pH of 4.0 in improving performance and in impacting Salmonella and necrotic enteritis is that by acidifying the ingesta in the crop, that low-pH contact time lost to impaired gizzard reflux is being compensated for.

Will LS-PWT2 clog my drinker lines?

No. It is the debris being dislodged from the dirty drinker system that could possible clog the lines if it isn’t flushed out promptly and thoroughly.

How long should I leave LS-PWT2 in the lines when I clean between flocks?

The first time you use LS-PWT2® in a house for cleaning, it should only be left in the lines about 8 hours due to the large amounts of debris that is removed during the cleaning process. This will facilitate the removal of this gelatinous material from the drinker system. After LS-PWT2® has been used to clean the drinker system, then it can be left in the lines as long as 24 hours prior to flushing.

How often should I clean my drinkers?

At the end of every flock and after running any type of water additive such as electrolytes or vitamins.

Should LS-PWT2 be run after I use electrolytes or vitamins?

Yes. This will remove any residual material from the water additives that can be a food source for bacteria.

Is LS-PWT2 approved for animal consumption?

Yes. LS-PWT2® is approved by the FDA as an animal feed additive.
