There are 20 tests in the bottle and the directions come in English and Spanish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy phosphate matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePhosphate is food for algae. Even a low concentration gives algae something to live on, which is why a pool with good chlorine can still go cloudy or green. Testing tells you whether the problem is sanitizer or nutrient, and that changes what you buy next.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow to use the reading\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTest once a week. Phosphate levels can jump after rain, after wind blows leaves and dirt into the water, or after a heavy weekend of swimmers, so one reading in spring does not describe the rest of the season. Note the number each week and watch the direction it moves, not just the single value.\u003c\/p\u003e\u003cp\u003eThis phosphate product is sold in the United States only.\u003c\/p\u003e","brand":"AquaChek","offers":[{"title":"Default Title","offer_id":48634693812436,"sku":"AQC-47-2227","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_aab045da-1143-4e72-960f-389d6819ee75.jpg?v=1788836373","url":"https:\/\/www.activepoolsupply.com\/products\/phosphate-test-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
