This product adds carbonate alkalinity to pool water, reducing pH drift and helping to prevent scale buildup, metal corrosion and surface etching. It dissolves readily when added while the pump runs and is simple to measure using standard pool test kits.\u003c\/p\u003e\n\n\u003ch3\u003eHow much alkalinity will this product add to my pool?\u003c\/h3\u003e\n\u003cp\u003eThe concentrate is sodium bicarbonate; dosage depends on pool volume. As a guideline, roughly 11 ounces of this product will raise total alkalinity by about 10 ppm in 5,000 gallons of water. Always confirm with a test kit and adjust gradually rather than making a single large addition.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e11 oz raises TA ~10 ppm per 5,000 gallons\u003c\/li\u003e\n  \u003cli\u003eMeasure current alkalinity before dosing\u003c\/li\u003e\n  \u003cli\u003eAdd in stages and retest after full circulation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere and how should I add the alkalinity increaser?\u003c\/h3\u003e\n\u003cp\u003eAdd the powder directly to the pool with the pump and filter running to ensure rapid distribution and dissolution.

Balanced alkalinity reduces pH swings that can cause cloudy water or inefficient disinfectant action. Proper alkalinity also helps keep chemical maintenance more predictable week to week.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces pH “bounce” for steadier water chemistry\u003c\/li\u003e\n  \u003cli\u003eHelps prevent scale, staining and plaster etching\u003c\/li\u003e\n  \u003cli\u003eImproves sanitizer effectiveness and clarity\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre there recommended alkalinity ranges for different pool surfaces?\u003c\/h3\u003e\n\u003cp\u003eYes — the ideal total alkalinity varies by pool construction. Fiberglass pools typically call for lower alkalinity than vinyl or plaster finishes. Use the following target ranges and adjust to the low end if your pool tends to carbonate or scale.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFiberglass: 70–100 ppm\u003c\/li\u003e\n  \u003cli\u003eMarcite, painted, tile, exposed aggregate: 80–120 ppm\u003c\/li\u003e\n  \u003cli\u003eVinyl: 120–140 ppm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Pool Mate 25-Pounds Premium Alkalinity Increaser is intended for pool owners, service professionals and property managers who need a reliable way to raise and stabilize total alkalinity. It suits all common pool types — vinyl, fiberglass, plaster and tile — and is especially useful when pH fluctuates frequently or when test results show alkalinity below recommended ranges.
