This product can be applied in several ways: by casting copper crystals directly over floating algae mats, dissolving them in water to spray, or placing the crystals in a porous bag to drag behind a boat. To ensure safety and prevent oxygen depletion, it is recommended to treat a portion of the pond at a time. The crystals come in a convenient ready-to-use 5 lb. pour container, designed to cover an area of 1 acre with a water depth of 1 foot. This makes it easy to manage algae growth efficiently and effectively. \n\nModel Number:","brand":"Crystal Blue","offers":[{"title":"Default Title","offer_id":46633977413795,"sku":"769715","price":31.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/2469\/7763\/files\/31e98c71ee89541640e0bad9a505f6dfd5137e95_769715_1_H.png?v=1776496298","url":"https:\/\/www.hartvillehardware.com\/products\/crystal-blue-copper-sulfate-smart-crystals-moss-algae-killer-5-lb","provider":"Hartville Hardware","version":"1.0","type":"link"}
