Due to excess planktons \u0026amp; increase in the total biomass quantity the Dissolved Oxygen (DO) consumption increases constantly causing low DO level in the pond bottom. Due to the decrease in DO in pond bottom aerobic beneficial bacteria cannot survive resulting in increase of anaerobic bacterial population. The Anaerobic bacterial population utilizes the excess organic matter for surviving and growth, resulting in the release of unwanted products in to the pond environment such as noxious gases like ammonia, hydrogen sulphide, nitrites and nitrates which further depletes the DO and enhances some unwanted phytoplankton groups like Blue green algae.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe Advantages of OSWA 4X-PS\u003cbr\u003e1. Reduces obnoxious odors, by removing hydrogen sulphide (H2S ) build-up in the pond.\u003cbr\u003e2. It plays a major role in water purification by organic matter degradation.\u003cbr\u003e3. Controls the ammonia levels in the pond water.\u003cbr\u003e4. Promotes growth of beneficial phytoplankton and stabilizes the bloom and pH.\u003cbr\u003e5. Effective in a wide range of pH and salinity.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eDosage\u003cbr\u003eFor Shrimp: 4 – 5 litres per acre in one meter depth\u003cbr\u003eFor Fish - 1 litre per acre\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eDosage:\u003cbr\u003e1. Reducing Ammonia and Nitrite levels\u003cbr\u003eAmmonia, Nitrite and Nitrate are toxics resulting from dead plankton or algae, residual feed, shrimp faeces and other decaying matter. When the concentration of beneficial microorganisms digesting organic matter is insufficient, the D.O. level is reduced and the water gets increasingly polluted - promoting growth of pathogens and harmful algae.\u003cbr\u003eRecommendation: Apply OSWA 4X-PS 2 – 3 litres per acre between 6-8 p.m.\u003cbr\u003e2. Algae or Plankton crash\u003cbr\u003eRebuild the plankton\/algae profile by using OSWA 4X-PS every morning at 9-12 AM with normal dosage until the profile is built up and stable.\u003cbr\u003e3. Addressing problem of blooming zooplankton\u003cbr\u003eThe water can be observed to have brown color.\u003c\/p\u003e\n\u003cp\u003eRecommendation: Use 3 litres per hectare in the morning between 9-12 a.m. The water color will improve and change into green within 5 days.\u003cbr\u003e4. Much organic wastes are suspended in the water\u003cbr\u003eRecommendation: Apply 4 -5 litres per acre any time of day.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eOther Advantages\u003cbr\u003e1. Works effectively in a wide range of salinity (0-50 ppt.), pH (5.0-9.5) and turbidity.\u003cbr\u003e2. Reduces the farmer’s costs on chemicals and drugs\u003cbr\u003e3. Effectively removes pond bottom sludge within 3-4 days\u003cbr\u003e4. Does not require fermenting before usage and the bacteria multiplies quickly from the time it is applied to the pond.\u003cbr\u003e5. Helps improve water quality by reducing ammonia and nitrite levels to non-toxic levels.\u003cbr\u003e6. Highly concentrated containing microorganisms at least 4 x 109 CFU\/ml.\u003cbr\u003e7. Can be applied at any time of day and works effectively both in aerobic and anaerobic conditions.\u003cbr\u003e8. It is environmental friendly and does not leave any toxic chemical substances in shrimp or the environment.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eEffects on water\u003cbr\u003eResults in a nice green water color by promotion of Chlorella, Nitzschia or Chitoceros. It also improves the water quality by controlling pH, reducing ammonia and nitrite levels within 2- 3 days and eliminating suspended organic matter in the pond water. If there are bubbles in the water, they will also disappear.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eEffects on Soil quality\u003cbr\u003eAfter harvest, it can be observed that there is a very low level of sediments or sludge at the pond bottom. Moreover, there are no bad odours coming from the soil. Regular use allows the microorganisms of OSWA 4X-PS to improve the soil by digestion of organic waste matter, and eliminating ammonia and nitrites. Succeeding pond preparation become easier and of higher quality.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eEffects on Growth\u003cbr\u003eOSWA 4X-PS indirectly improves survival rate and average daily growth rate due to its properties. By balancing pond water and soil environment, optimal conditions for shrimps to live and grow are achieved.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eControl against Diseases\u003cbr\u003eResearch in lab and on the field has shown that OSWA 4X-PS prevents and treats black gills problem by clearing the black soil formation.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eMode of Action:\u003cbr\u003e1. The probiotics species present are facultative anaerobes which survive and consume less oxygen.\u003cbr\u003e2. Probiotics species present intakes the organic matter and black soil as food and consume them for proliferation and growth thus reducing the load of organic matter and black soil.\u003cbr\u003e3. The consumed waste matters are digested and harmless and useful products are released in to the pond ecology which facilitates the growth of beneficial planktons.\u003cbr\u003e4. Once the waste organic matter depletes from the pond environment the anaerobic bacteria \u0026amp; Blue green algae cannot survive due to lack of food thus increasing the transparency.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":41495079092282,"sku":null,"price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/2207\/2122\/files\/ChatGPTImageMay19_2026_12_56_45AM.png?v=1782821690","url":"https:\/\/lakenlawn.com\/products\/oswa-4x-ps","provider":"My Store","version":"1.0","type":"link"}
