BENEFITS OF CHLORIDES

1. In ponds, Chlorides functions to minimize the rise in pH that can occur when photosynthesis
2. Calcium ions react at elevated pH to precipitate carbonate ions as calcium carbonate, and this reaction minimizes the amount of carbonate in the water to hydrolyse and increase pH.
3. Calcium and magnesium ions tends to neutralize the negative charges on suspended clay particles, allowing them to floc together and create a mass great enough to precipitate.
Calcium sulfate often is applied to ponds to clear turbidity from the water.
4. Calcium ions affect the toxicity of trace metals to prwn and other aquaculture species. The presence of calcium blocks the uptake of metal ions across the gills, thereby increasing the dissolved concentration of metals required to cause a toxic effect.
