Frequently Asked Questions About low pH pool problems acid damage
Q: What happens if pool pH is too low?
A: Low pH (below 7.2) creates acidic water that causes: equipment corrosion (pumps, heaters, metal fittings), plaster etching and pitting, concrete deterioration, eye and skin irritation, rapid chlorine dissipation, metal staining from dissolved copper/iron. pH below 7.0 causes severe damage within days. Equipment replacement costs thousands.

Q: How do I raise low pH in my pool?
A: Raise pH safely: First, increase total alkalinity to 80-120 ppm using sodium bicarbonate (1.5 lbs per 10,000 gallons raises TA 10 ppm). Second, if pH still low, add sodium carbonate (pH increaser) - 6 oz per 10,000 gallons raises pH 0.2 points. Add chemicals in stages, wait 6 hours between additions, test frequently.

Q: What causes pool pH to drop?
A: pH drops from: heavy rain (especially acid rain), acidic chlorine products (trichlor tabs, dichlor shock), overuse of muriatic acid, automatic acid feeder malfunction, naturally acidic source water, high bather loads producing acids. Each trichlor tab can drop pH by 0.1-0.2 points.

Q: How low is too low for pool pH?
A: pH safety levels: 7.4-7.6 ideal, 7.2-7.4 acceptable, 7.0-7.2 problematic (correction needed), 6.8-7.0 damaging (equipment corrosion active), below 6.8 critical (severe damage occurring). Never allow pH below 7.0 for extended periods. Emergency correction needed under 6.8.

Q: Can you swim in low pH pool water?
A: Swimming in low pH water is unpleasant and potentially harmful: causes burning eyes and skin irritation, dries out skin and hair, can trigger respiratory issues in sensitive people, indicates aggressive water damaging equipment. While brief exposure isn't dangerous, extended swimming uncomfortable and pools need immediate correction.

Q: What's the difference between pH increaser and alkalinity increaser?
A: Alkalinity increaser (sodium bicarbonate) raises both alkalinity and pH gradually, providing pH buffer stability. pH increaser (sodium carbonate) raises pH directly with minimal alkalinity change. Always raise alkalinity first to 80-120 ppm, then fine-tune pH if needed. Alkalinity prevents pH swings.

Q: How much pH increaser do I need?
A: pH increaser dosage: 6 ounces per 10,000 gallons raises pH by approximately 0.2 points. Never add more than 2 pounds at once (can cause scaling). Add in stages, wait 6 hours between doses, retest before adding more. Large corrections may require multiple treatments over 24-48 hours.

Q: Why does my pool pH keep dropping?
A: Recurring low pH indicates ongoing acid source: overuse of trichlor tabs or dichlor shock, automatic acid feeder problems, acid rain in your area, low alkalinity (insufficient buffer), naturally acidic source water. Fix the source - just raising pH repeatedly doesn't solve the underlying problem causing the drops.
Answer verified by CoOpPools expert technicians who are worker-owners with extensive training and experience.
Q: How fast can I raise pool pH?
A: Raise pH gradually for safety: maximum 0.2 points per hour, never more than 0.4 points per day unless emergency. Large, rapid increases can cause scaling and water cloudiness. For pH below 7.0, contact professional for emergency correction. Patience prevents additional problems from over-correction.

Q: How much does it cost to fix low pH?
A: Low pH correction costs $50-300: DIY chemicals (sodium bicarbonate, sodium carbonate) cost $25-75, professional correction service $125-300. However, damage from untreated low pH costs thousands: heater replacement $1,500-4,000, pump replacement $500-2,000, plaster refinishing $3,000-8,000. CoOpPools prevents costly damage through proactive pH management and emergency correction services.
