Zeolite aqua ph zeolite aqua ph. - reduces acidity of soil and water in aquaculture ponds, thereby enhancing the growth and survival rate of fish, prawn and shrimp. zeolite aqua ph. - stabilizes water ph and promotes biological productivity. Zeolite aqua ph. - kills most microorganisms, especially parasites at the time of pond preparation. water ph is one of the most critical chemical parameters for prawn and shrimp farming. The optimum water ph range in the prawn and shrimp pond is 7.5 to 8.5. It is essential to stabilize the ph within this range. The ph value in the water is normally lowest in the morning and highest in the afternoon. For best water quality, the maximum diurnal ph fluctuation should not exceed 0.5. the main factor that affects the ph variation in the water is the alkalinity. Pond water should contain 50 ppm to 75 ppm total alkalinity and total hardness for good growth of prawn and shrimp. advantages of zeolite aqua ph. •prevents extreme changes in ph. •improves growth of shrimp and prawn due to control of the nervous system or the functions of muscles. •improves shell formation in prawn and shrimp. •increases survival rate of prawn and shrimp and helps achieve proper growth and moulting. •kills most microorganisms, especially parasites, due to caustic reaction. Improves water quality. •precipitates suspended or soluble organic materials. •helps in proper osmoregulation in prawn and shrimp. •enhances chlorophyll component in phytoplankton. •prevents convulsions from magnesium tetany in fish. usage: zeolite aqua ph. -should be applied every other day until the ph value become more stable and does not vary more than 0.5. dosage: 10.0 to 40.0 kg zeolite aqua ph. - per acre or as advised by aquaculture consultant. spread zeolite aqua ph. - aqua evenly throughout the pond. presentation: 40 kg hmhd bag.
