Admiral Liquid for aquatic algae and weed control enhances the appearance of water features with a blue colorant, while also controlling the growth of several types of aquatic weeds and algae. With the highest pure dye actives of all EPA-registered lake colorants, Admiral Liquid’s formulation produces a higher quality, longer lasting color. When applied early in the weed growth season, Admiral Liquid can help keep your water features free from unattractive nuisance plants. Use Admiral Liquid in conjunction with Lake Pak WSP biological clarifier for an effective nutrient management and water clarity improvement program. With both liquid and WSP (water soluble packet) formulations, Admiral Liquid is convenient for every water feature. Apply liquid directly from the container, near the shoreline. Our unique WSP is a highly concentrated, premeasured, dry formula that disperses evenly as it dissolves in the water body.
