BioGuard Lo’N’Slo 1.5kg – Pool pH & Alkalinity Decreaser

BioGuard Lo’N’Slo 1.5kg – Pool pH & Alkalinity Decreaser

BioGuard Lo’N’Slo is a granular pool pH and Total Alkalinity decreaser designed to help restore correctly balanced swimming pool water.

High pH and alkalinity can contribute to cloudy water, scale formation and reduced chlorine efficiency. Lo’N’Slo provides a convenient alternative to liquid pool acid for making controlled water-balance adjustments.

Why Use BioGuard Lo’N’Slo?

BioGuard Lo’N’Slo:

• Lowers high pool pH
• Reduces high Total Alkalinity
• Helps prevent scale formation
• Helps reduce cloudy water caused by poor balance
• Supports more effective chlorine sanitation
• Suitable for all pool types
• Provides an easier-to-handle alternative to liquid acid

When Should I Use Lo’N’Slo?

Use Lo’N’Slo when testing shows that your pool water has:

• High pH
• High Total Alkalinity
• Or both

BioGuard generally recommends maintaining pool pH around 7.2–7.6.

Always test the water before making adjustments.

What Problems Can High Pool pH Cause?

High pH can contribute to:

• Cloudy or dull-looking pool water
• Scale on pool surfaces and equipment
• Reduced chlorine effectiveness
• Increased chemical demand
• Dirty or scaled filters

Correcting the pH can help restore more effective sanitation and improve overall water quality.

What About High Total Alkalinity?

Total Alkalinity helps stabilise pH, but when it becomes too high it can make pH difficult to control.

Lo’N’Slo can be used to lower Total Alkalinity as part of a controlled water-balance program.

Make gradual adjustments and retest between treatments rather than trying to correct a large imbalance all at once.

Granular pH Decreaser vs Liquid Pool Acid

Lo’N’Slo is a dry granular product based on sodium hydrogen sulphate.

For customers who prefer not to handle liquid hydrochloric or muriatic acid, it provides a practical way to reduce pool pH and alkalinity while following the product label directions.

How Much Lo’N’Slo Should I Add?

The amount required depends on:

• Pool volume
• Current pH
• Current Total Alkalinity
• Desired adjustment

Always follow the dosage instructions on the product label and circulate the pool water during treatment as directed.

Retest before making further adjustments.
