I maintain a 30 ft by 20ft pond for my grandma and i keep koi in it. There was a breakout of fish lice once and while a few brands of medications failed me, Jungle labs as recommended by someone who used it before. It save the 30 kois in the pond. took only 1 dose but gave it another dose after a week just to be sure. At that time, the very effective waterlife parazin was not available yet.
