The Pond Guy InstaFix Algae Control helps you stop algae. InstaFix is an EPA registered algaecide that eliminates existing algae growth and helps control future growth. InstaFIx works to dissolve algae in a fountain, backyard pond, water garden with liner, water feature, pondless waterfall, fishpond, or decorative pond without any outflow. When used as directed, will not harm aquatic wildlife such as a frog, turtle, dog, duck or other animal. Do not use InstaFix algae killer with snails, shrimp, clams and other crustaceans, or mollusks. Will not harm pond equipment such as any skimmer, pump, filter, ultraviolet clarifier, or electric powered aeration system. Will not harm any lily pad or ornamental floating plant. Our easy-to-use algae concentrate is made to fix algae problems. InstaFix is an EPA registered algae eliminator with an easy-to-apply chemical formula. Simply pour liquid evenly around the pond’s edge or into an area with the greatest circulation. Once pond algae growth is under control, weekly doses will control light algae growth and reduce pond maintenance. Before using InstaFix algae destroyer, ensure water is well aerated via a waterfall, fountain, or other method to prevent fish loss. Aeration must be continuous. Use 1 fl oz of InstaFix per 360 gallons of pond water. Formulated for freshwater ponds, pondless waterfalls, and indoor and outdoor water features. It is highly recommended to remove excess algae prior to your treatment. Remove any organic debris before it can settle at the bottom and decompose into pond muck, sludge and scum. Once algae is under control, we recommend following up with Clarity Defense flocculant treatment. Clarity Defense water clarifier is designed to clear cloudy, murky pond water quickly, leaving you with crystal clear water.
