Each strip reads biguanide level, pH and total alkalinity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow the test works\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUnlike a single dip strip, this one is a two part test. Dip the strip and read the total alkalinity and pH pads first. Then re dip the same strip, moving it back and forth underwater for a full 30 seconds, and read the biguanide pad. The longer second immersion is what develops the biguanide color, so cutting it short gives a low reading.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKeeping records\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAquaChek advises testing at least weekly and writing down the results. Biguanide water tends to drift rather than crash, and a column of numbers makes a slow slide obvious weeks before the water tells you. Complete instructions are included in 15 languages: English, French, Spanish, Italian, Czech, Danish, Dutch, German, Greek, Hungarian, Polish, Portuguese, Russian, Swedish and Turkish.\u003c\/p\u003e","brand":"AquaChek","offers":[{"title":"Default Title","offer_id":48634608746708,"sku":"AQC-45-112","price":20.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_8ef7050e-5f06-4fe6-93c4-fe3ab5e527b6.jpg?v=1788835378","url":"https:\/\/www.activepoolsupply.com\/products\/biguanide-blue-test-strips","provider":"Active Pool Supply","version":"1.0","type":"link"}
