{"product_id":"alum-5-lb","title":"Bio-Dex Alum Aluminum Sulfate Clarifier, 5 lb.","description":"\u003cp\u003eBio-Dex AL125 is alum, aluminum sulfate, supplied in a 5 lb. container. Bio-Dex classifies it as a clarifier, and it works as a flocculant.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a flocculant does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOrdinary clarifiers help the filter catch fine particles. A flocculant works differently: it binds heavy metals and suspended debris into clumps heavy enough to come out of suspension, which is why alum is reached for when water has gone cloudy and normal filtration has not fixed it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat to expect\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eBecause alum drops what it collects rather than holding it for the filter, plan on removing the settled material afterward. Bio-Dex lists this product for above ground and in ground pools, residential and commercial water, spas and hot tubs, and fountains.\u003c\/p\u003e","brand":"Bio-dex Laboratories","offers":[{"title":"Default Title","offer_id":48634470924500,"sku":"BDL-50-195","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_e2bf5d82-3e5b-433e-81cf-6cbd4f6c3454.jpg?v=1788831653","url":"https:\/\/www.activepoolsupply.com\/products\/alum-5-lb","provider":"Active Pool Supply","version":"1.0","type":"link"}
