Soft water with low alkalinity,Then, using Dolomite powder sprinkled on the water will work-Neutralize acid, increase pH of water and pond bottom,Increase CO2 for photosynthesis of phyto-plankton,Increased phosphorus content in the bottom, reducing dissolved phosphorus.Provides macro-nutrients such as Ca, Mg, P, Na, K, Cl and trace elements such as Fe, Mn, B, Mo, Cu, Co, Zn. Dolomite is one of the indispensable ingredients in the field of aquaculture.Dolomite is used to treat water, increase the alkalinity of water, provide trace elements and macro nutrients for fish feed and create an environment for algae to grow.During aquaculture, the pH of the pond continuously decreases, the composition of macro nutrients and micro nutrients need to be added to create a suitable environment for aquatic and algae useful growth; Therefore, it is often necessary to sprinkle with Dolomite powder.The amount of Dolomite powder sprinkled periodically should be based on the pH of water.
