Shore-Klear or AquaStar can be mixed with a surfactant and water and sprayed on the pads that you want to kill. This enables you to spot treat, leaving water lilies in areas where you want them and removing them from areas where they interfere with your pond use. These are safe products that will not harm your fish and are registered with the EPA for aquatic use.
