Lab tests and previous smaller-scale field tests indicate that the phoslock is capable of removing more than 90 percent of the phosphorus available to algae. We know this technique works in the test tube, in a fish tank and a large tank. The researchers will measure levels of phosphorus in the water and sediments before and after the application of phoslock. They will also monitor its effect on algae, fish and water quality. The phoslock is a kind of stopgap that must be supported by urgent measures to cut the flow of nutrients entering the water.
Algae blooms can be deadly to fish and plants.
They also can cause poisoning in livestock and humans. They emit bad odors and drive up water-treatment costs. High nutrient levels cause populations of algae to explode through a process known as eutrophication. All Rights Reserved. Terms under which this service is provided to you.
