It is an algaecide: it is there to kill algae in the pool and to keep it from taking hold again.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat quat means\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eQuat is shorthand for quaternary ammonium compound, one of the long established families of pool algaecide. Quats are non metallic, which is the practical point for most owners: unlike a copper based product, there is no metal going into the water with it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReading the 50 percent\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 50% on the label is the concentration of the active ingredient in the bottle. It is a strength figure, not a dose, and it should not be read as any guide to how much to add.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe one habit worth having\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eQuat algaecides are known for foaming when too much of them ends up in the water. Nothing about that is exotic, it is simply how the chemistry behaves, and it is easy to avoid by staying inside what the container label allows. Read the label that comes with your bottle before you open it, and let it set the amounts.\u003c\/p\u003e","brand":"Biolab","offers":[{"title":"Default Title","offer_id":48634527350996,"sku":"EZC-50-1064","price":28.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_edef436b-2a7b-4f82-9187-3e3cb4515d70.png?v=1788833885","url":"https:\/\/www.activepoolsupply.com\/products\/1-qt-algaecide-50-quat","provider":"Active Pool Supply","version":"1.0","type":"link"}
