PoolFix Alkalinity Increaser 10 lb Bag — Sodium Bicarbonate for Pools, Stabilizes pH & Clears Water

PoolFix Alkalinity Increaser is a 10 lb bag of 100% pure sodium bicarbonate formulated to raise total alkalinity and help stabilize pool pH for clearer, more comfortable water.

Keeping total alkalinity in the recommended range is one of the easiest ways to prevent rapid pH swings, reduce surface wear, and maintain consistent sanitizer performance. PoolFix delivers a high-purity baking soda formula in a resealable bucket so you can quickly correct low alkalinity in both above-ground and inground pools, without introducing additives or filler ingredients.

How quickly will PoolFix raise my pool's alkalinity?

Most pools see measurable increases in total alkalinity within a few hours after application, with full dispersion typically by the next circulation cycle. For best results add with the pump running and spread the powder around the perimeter or broadcast over the skimmer for even mixing.

• Add while the filtration system is running to speed dissolution.
• Brush or circulate the water gently to distribute the product.
• Re-test alkalinity after 4–8 hours and again the following day.

Will this product affect my pool's pH and water clarity?

Raising alkalinity with sodium bicarbonate tends to buffer pH, making it less prone to rapid change; because the formula is pure baking soda, it increases alkalinity with a modest pH impact. Proper use helps reduce cloudiness caused by chemistry swings and lowers the risk of scale or corrosion from unbalanced water.

• Designed to stabilize pH by strengthening the water’s buffering capacity.
• Helps prevent cloudy water associated with frequent pH shifts.
• Does not contain additives that can leave residues or affect clarity.

How much do I need and how do I apply it safely?

Dosage depends on pool volume and current alkalinity level; typical adjustments are made in pounds per 10,000 gallons. Always test before adding, add gradually, and avoid dumping large amounts in one spot—spread evenly with the pump running and retest after full circulation.

• Consult pool volume and test kit results to calculate exact dose.
• Add in small increments, retesting between additions to avoid overshoot.
• Wear gloves and avoid inhalation; keep the resealable bucket closed and dry.

What surfaces and pools is PoolFix suitable for?

This sodium bicarbonate formula is safe for most pool types including concrete/plaster, tile, vinyl liners, and fiberglass when used as directed. Regular alkalinity maintenance helps protect plaster, tile grout, and metal equipment from damage caused by unstable water chemistry.

• Recommended for both above-ground and inground pool systems.
• Helps protect plaster, tile, liners, and pool hardware.
• Non-corrosive, filler-free formula that won’t introduce unknown compounds.

Who is this for: PoolFix Alkalinity Increaser is aimed at pool owners, maintenance professionals, and seasonal openers who want a straightforward, high-purity baking soda product to correct low alkalinity and improve water stability. If you test regularly, seek predictable chemistry, and prefer a simple resealable 10 lb bucket for easy storage and handling, this product fits those needs.
