Low pH is the silent destroyer of pool equipment, makes chlorine over-aggressive, and turns swims into eye-stingers.

If pH reads below 7.2 you need pH Increaser. Symptoms of low pH include stingy eyes, corroded metal fittings, etched plaster, and aggressive chlorine smell.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eHow long does it take to work?\u003cbr\u003epH typically stabilises 4 to 6 hours after dosing with the pump running. Always wait this long before retesting and adding more.\u003c\/p\u003e\n\u003cp\u003eCan I add too much?\u003cbr\u003eYes. Over-dosing pushes pH above 7.6, where chlorine becomes less effective and water can turn cloudy. Dose conservatively, retest, then add more if needed.\u003c\/p\u003e\n\u003cp\u003eIs this the same as alkalinity increaser? \u003c\/p\u003e\n\u003cp\u003eNo. pH Increaser (sodium carbonate) raises pH and slightly raises alkalinity. Alkalinity Increaser (sodium bicarbonate) raises alkalinity primarily with a smaller pH effect. Most UK owners only need pH Increaser unless alkalinity is specifically low.\u003c\/p\u003e\n\u003cp\u003eCan I use this in a hot tub?\u003cbr\u003eYes. Use the same target range (pH 7.2 to 7.6) and dose at approximately 10g per 1,000L of spa water as a starting point. Always retest before re-dosing.\u003cbr\u003e\u003c\/p\u003e","brand":"CrystaLux","offers":[{"title":"Default Title","offer_id":54035867959629,"sku":"CLX-PHI-5KG","price":14.95,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/1669\/4605\/files\/CrystaLuxpHPluspHIncreaser5kg.jpg?v=1785506092"},{"product_id":"crystalux-ph-minus-7kg","title":"CrystaLux pH Minus 7kg Pool \u0026 Spa pH Reducer","description":"\u003cp\u003ePull pH back into the safe zone, fast.\u003cbr\u003e\u003cbr\u003eCrystaLux pH Reducer is dry-acid sodium bisulphate granules that bring pool and spa pH back down into the 7.2 to 7.6 target range.

Test pH and total alkalinity before dosing. Target pH is 7.2 to 7.6. Typical total alkalinity target is 80 to 120 ppm. 2. Pre-dissolve granules in a clean bucket of pool water. 3. Add slowly with the pump running, distributed around the perimeter for general pH correction. 4.

High total alkalinity correction: use smaller repeated doses, retest between applications, and avoid driving pH too low. Aeration can help raise pH again without adding alkalinity. Always retest before re-dosing. Do not add large doses in one hit.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cbr\u003eWhy is my pH always high?\u003cbr\u003eHigh pH commonly comes from new plaster pools curing, hard fill water, frequent splash-out and top-ups, or aerators and water features off-gassing CO2. The fix is regular pH Reducer dosing, ideally with weekly testing.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eHow is this different from muriatic acid?\u003cbr\u003eSodium bisulphate is dry granular acid, easier and safer to store and dose than liquid muriatic (hydrochloric) acid. It is the standard for residential pool care in the UK.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eCan I use this with my salt chlorinator?\u003cbr\u003eYes. Salt pools tend to drift to higher pH because the cell off-gases CO2; pH Reducer is a frequent need for salt chlorinator owners.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eWill it lower alkalinity too?\u003cbr\u003eYes, it lowers both pH and alkalinity. If alkalinity is in range and only pH is high, dose conservatively to avoid pulling alkalinity below 80 ppm.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eHow long will 7kg last?\u003cbr\u003eFor a typical 50,000L UK pool with seasonal use, a 7 kg pack covers approximately one full season of routine pH corrections.\u003c\/p\u003e","brand":"CrystaLux","offers":[{"title":"Default Title","offer_id":54035868057933,"sku":"CLX-PHR-7KG","price":19.95,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/1669\/4605\/files\/pHMinus7kg.jpg?v=1785506092"}],"url":"https:\/\/poolchemicalsstore.co.uk\/collections\/ph-balancers.oembed","provider":"Pool Chemicals Store","version":"1.0","type":"link"}
