SpaPure Liquid pH Plus | Spa Liquid pH Increaser

• 1 x SpaPure Liquid pH Plus (1 pint / 16 fl oz / 473 mL, ready-to-use pour bottle)

• Raises low pH fast — quickly brings acidic water back into the safe 7.2–7.6 range
• Ready to use — liquid pour formula, no mixing or dissolving
• Protects your spa — prevents the corrosion and equipment damage acidic water causes
• Ensures clarity and comfort — balanced pH means clearer water and gentler soaks
• Helps your sanitizer work — chlorine and bromine perform best at proper pH
• Universally compatible — works with all spa sanitation systems

Liquid pH Plus neutralizes the acidity in your water, raising pH into the comfortable, non-corrosive range. Aim for a pH of 7.2–7.6, where the water is gentle on your spa and your skin and where your sanitizer does its job efficiently.

It does the same work as granular pH Up, with one practical difference: because it's already in solution, it disperses the instant it hits the water — no waiting for granules to dissolve and no risk of dry product resting on the shell. Pour it in near a return jet with the pump running and it mixes immediately. The spa can be used right after application.

Pro Tip: Balance alkalinity before pH. Total alkalinity is the buffer that holds pH steady, so if your pH keeps drifting low no matter how much pH Plus you add, the real issue is usually low alkalinity. Set alkalinity into range first with an alkalinity increaser, and you'll find pH becomes far easier to raise and keep stable.

Never mix different products together in the same bottle or pail. Add this product directly to the spa water with the circulation system running. Only use when pH is below 7.2. Aim for a pH of 7.2–7.6. Always follow the bottle label for exact dosing.

1. Turn on the circulation system.
2. If pH is between 7.0 and 7.1, add 1/2 ounce per 100 gallons of water, pouring directly into the spa near a return jet.
3. If pH is below 7.0, add 1 ounce per 100 gallons.
4. The spa may be used immediately after application.
5. Wait about 30 minutes, then retest. If pH is still below 7.2, repeat until it sits between 7.2 and 7.6.

Pro Tip: Add it slowly near a return jet, not into still water. A liquid balancer disperses best into moving water, and adding it gradually lets you sneak up on your target pH instead of overshooting into high-pH territory (which brings its own problems — scale and cloudy water). Pour, circulate, retest, repeat.

SpaPure Liquid pH Plus is compatible with all spa sanitation systems — chlorine, bromine, salt, mineral, and ozone. As a balancer, it's part of the foundation you maintain alongside your sanitizer, regardless of how you sanitize.

It's the liquid alternative to granular pH Up, and the counterpart to a pH decreaser (Liquid pH Minus or granular pH Down) for when pH climbs too high. It works alongside an alkalinity increaser and SpaPure test strips. Balance pH and total alkalinity before adding sanitizing and shock products. Never mix it with other chemicals in the same bottle or pail — add it directly to the spa water.
