Alkalinity Plus by EcoOne — Natural Spa Alkalinity Increaser (Chlorine-Free, Phosphate-Free) 2 lb

Balanced spa water, naturally

EcoOne Alkalinity Plus is a natural granular powder designed to gently raise your hot tub's total alkalinity using only sodium bicarbonate. It contains no chlorine and no phosphates, helping keep the water clear and comfortable without harsh residues. The skin-friendly formula supports a neutral feel in the water, making your soak more pleasant while reducing the likelihood of irritating sensations around the eyes or skin.

With balanced alkalinity, you may experience more stable pH behavior, smoother water feel, and less frequent fluctuations that can lead to cloudy water or mineral buildup. This approach aligns with EcoOne’s eco-conscious spa care range, which prioritizes effective balance without relying on harsh additives. The result is water that looks clearer and more inviting, while helping protect spa surfaces, heating elements, and filtration components from unnecessary stress.

How to use Alkalinity Plus

Keep monitoring the spa’s total alkalinity (TA) and follow these steps for best results:

• Test the TA level before adding any product
• If TA is below 75 ppm, add 2–3 tablespoons directly to the water
• Allow the water to circulate for several hours with the pump running
• Retest and repeat until TA sits between 80–120 ppm

Using the product as directed helps maintain a stable baseline, which can support consistent pH management and clear water. Results may vary based on your pool or spa setup and usage patterns.

Why balance matters

While water balance is not a guarantee of specific outcomes, stable alkalinity often correlates with smoother pH control, fewer scale formations, and a more comfortable soak experience. EcoOne’s approach focuses on natural balance to support your spa’s comfort and longevity.
