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.
Beware Liqueur... Liquor is made by distilling a grain, which means converting its carbohydrates to alcohol via fermentation. For this reason, distilled liquors, such as vodka, rum, and whiskey are at or near 100% efficiency (defined as percentage of calories from alcohol). Liqueur has added sugar, so watch out. Those calories can sneak up, just as those from mixers. Lets take a look at some common liquors and how efficient they are.
