Subtract one from the other and you have combined chlorine, the chloramine that builds up in a working pool and produces the strong chlorine smell and the stinging eyes that people wrongly blame on too much chlorine. A strip or an OTO kit will not show you that number, so the problem goes unfixed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is in the box\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe kit ships in the red display box with a Lucite test cell, 50 each of the DPD No. 1 and No. 3 tablets, 1 oz each of reagents No. 2 and No. 3, half an ounce each of No. 4 and No. 5, and the water test booklet. The acid demand test rounds it out by telling you how much acid to add rather than leaving you to guess.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48634473709780,"sku":"RAI-45-832","price":42.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_17eba3d9-1add-475a-b2d7-4920c4284619.jpg?v=1788831900","url":"https:\/\/www.activepoolsupply.com\/products\/all-in-one-dpd-test-kit-78dpd","provider":"Active Pool Supply","version":"1.0","type":"link"}
