When water is stagnant, has a high temperature or a high concentration of Nitrates and Phosphates, an algae bloom might occur, which can cause several problems. Blue-green algae growth, also known as cyanobacteria, can cause a foul odour to the water, a layer of scum on the surface and even pose a health risk. Green algae may colour the water green, look unclear and plants can die. Therefore an algae problem is often unwanted and algae control is desired.
1 An alcoholic beverage made by distillation rather than by fermentation. 2  A rich broth resulting from the prolonged cooking of meat or vegetables, especially greens. 3  Also called pot liquor. 4  An aqueous solution of a nonvolatile substance. 5  A solution, emulsion, or suspension for industrial use.
A distilled beverage, spirit, or liquor is an alcoholic beverage containing ethanol that is produced by distilling (i.e., concentrating by distillation) ethanol produced by means of fermenting grain, fruit, or vegetables. This excludes undistilled fermented beverages such as beer, wine, and cider. Vodka, gin, baijiu, tequila, rum, whisky, brandy, Singani and soju are examples of distilled beverages. Hard liquor is used in North America and India to distinguish distilled beverages from undistilled ones (implicitly weaker). 1  Spirits.
