BioGuard Lo’N’Slo 5kg – Pool pH & Alkalinity Decreaser

BioGuard Lo’N’Slo 5kg – Pool pH & Alkalinity Decreaser

BioGuard Lo’N’Slo is a granular pool pH and Total Alkalinity decreaser for correcting high pH and alkalinity in swimming pool water.

The 5kg pack is ideal for larger pools or customers who regularly maintain their own pool water and want a larger quantity on hand.

Why Use BioGuard Lo’N’Slo?

• Lowers high pool pH
• Reduces high Total Alkalinity
• Helps reduce scale formation
• Helps prevent cloudy water caused by poor water balance
• Supports more effective chlorine sanitation
• Suitable for all pool types
• Granular alternative to liquid pool acid
• Large 5kg pack for ongoing pool maintenance

When Should I Use Lo’N’Slo?

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

• High pH
• High Total Alkalinity
• Or both

Correct water balance helps your chlorine work effectively and reduces the likelihood of scale, cloudiness and equipment problems.

What Can High Pool pH Cause?

When pool pH is too high, you may experience:

• Cloudy or dull-looking water
• Scale on pool surfaces and equipment
• Reduced chlorine efficiency
• Increased chemical demand
• Scale build-up in filters and equipment

BioGuard recommends maintaining pool pH around the appropriate range for your pool surface and treatment program.

High Total Alkalinity

Total Alkalinity helps stabilise pH, but excessively high alkalinity can make pH difficult to control.

Lo’N’Slo can also be used to gradually reduce Total Alkalinity.

Make controlled adjustments and retest the water between treatments rather than attempting a large correction in one dose.

Why Choose the 5kg Pack?

The 5kg size is particularly suitable for:

• Larger swimming pools
• Regular pool maintenance
• Pools that frequently require pH reduction
• Customers who prefer keeping a larger supply of water-balancing chemicals available

For lower chemical usage or occasional adjustments, BioGuard Lo’N’Slo is also available in a 1.5kg pack.

Lo’N’Slo or Liquid Pool Acid?

Both products can be used to lower pool pH and Total Alkalinity.

BioGuard Lo’N’Slo is a dry granular sodium hydrogen sulphate product, making it a convenient alternative for customers who prefer not to handle liquid hydrochloric or muriatic acid.

How Much Should I Add?

The required dose depends on:

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

Always test the water first and follow the dosage instructions on the product label.

Circulate the pool water as directed and retest before making further adjustments.
