Acrylic Tank Manufacturing
Acrylic Tank Manufacturing's Agent Green is formulated with lanthanum chloride and acts as an ion exchanger, the company reports. It also uses calcium to bind phosphate into insoluble beads, because phosphate will not dissolve back into the water while waiting to be swept out by filtration, the company adds. The product is available in a 4-oz. bottle that treats 1,180 gal. at 1 ppm.
