The desired range for calcium hardness is as follows: Vinyl Pools: 200-300 ppm, Tile and Exposed Aggregate Pools: 200-400 ppm, Marcite, Fiberglass or Painted Pools: 250-400 ppm. If the calcium hardness tests less than the desired range, add this product according to the included chart. Place this product into a plastic bucket already filled with swimming pool water. Do this in a ration of up to 2 pounds of product per approximate 5-gallon bucket of water. Slowly pour this solution around the perimeter of the swimming pool while the circulating system is operating. In a 10,000 gallon pool, do not add more than 10 pounds of this product per 2 hour period.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEAN:\u003c\/b\u003e 0034261005757\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePackage Dimensions:\u003c\/b\u003e 12.4 x 12.3 x 6.6 inches\u003c\/p\u003e","brand":"Robelle","offers":[{"title":"Default Title","offer_id":44411785543766,"sku":"B01CP5S590","price":56.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/6471\/0742\/files\/71-WfsSJwvL.jpg?v=1775276236","url":"https:\/\/www.matildaco.com\/products\/robelle-16-pounds-premium-pool-calcium-up-calcium-hardness-increaser","provider":"Matilda Co","version":"1.0","type":"link"}
