Active chemistry: sodium carbonate (soda ash) — the industry-standard ingredient for raising spa water pH back into the ideal 7.2–7.8 range. Spa Up will also lift total alkalinity modestly as a secondary effect, making it a versatile balancing tool when both readings are running low.\u003c\/p\u003e\n\u003cp\u003epH is the single most important number on your test strip — more important than sanitizer level, more important than alkalinity, more important than hardness. When pH drifts low (below 7.2), three things happen at once: the water becomes corrosive to heater elements, pump seals, and metal jet hardware; chlorine and bromine become hyperactive and burn off faster, leaving you under-sanitized between doses; and bathers complain of stinging eyes and itchy skin. Left unaddressed, low pH can cause hundreds or thousands of dollars in equipment damage long before the water itself looks bad.\u003c\/p\u003e\n\u003cp\u003eSpa Up corrects low pH quickly and predictably. The granular formula dissolves in seconds with the jets running, and a single 1 oz. dose per 500 gallons typically moves pH a full point upward — enough for most routine corrections. Used as part of a weekly balance check with a quality test strip, Spa Up is one of the two essential pH tools every hot tub owner needs to keep on the shelf (the other being a pH decreaser for when the water runs the opposite direction).\u003c\/p\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cstrong\u003ePro Tip:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eAlways check\u003cspan\u003e \u003c\/span\u003e\u003cem\u003etotal alkalinity\u003c\/em\u003e\u003cspan\u003e \u003c\/span\u003ebefore adjusting pH. If alkalinity is low (below 80 ppm), pH will be unstable — it'll bounce up and down regardless of how much Spa Up you add, because there's not enough \"buffer\" in the water to hold a reading. Raise alkalinity first with a dedicated alkalinity increaser, let the spa circulate for 30 minutes, then come back and adjust pH with Spa Up. This single habit eliminates most of the \"I keep adding pH Up and nothing happens\" frustration.\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cstrong\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cp\u003e\u003cspan role=\"img\" aria-label=\"®\"\u003eLeisure Time®\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Leisure Time Spa","offers":[{"title":"Default Title","offer_id":4618851713061,"sku":"LTS03","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2507\/5288\/files\/leisure_time_spa_up_front.jpg?v=1757696418","url":"https:\/\/leisuretimeinc.com\/products\/spa-up-2-lbs","provider":"Leisure Time Inc.","version":"1.0","type":"link"}
