BAQUACIL® Swimming Pool Sanitizer and Algistat
Product Overview
A proven choice for homeowners seeking a chlorine-free environment without the stability issues of traditional sanitizers.
In our experience, BAQUACIL Swimming Pool Sanitizer and Algistat is the standard specification for biguanide-based systems, utilizing 20% Poly(hexamethylenebiguanide) hydrochloride to control bacteria and algae. This 1.89 Liters container is designed to maintain a stable 50 ppm concentration, offering a high level of stability in water that isn't affected by sunlight or pH fluctuations like chlorine. It provides a consistent sanitizing effect without the common side effects of chloramines, such as eye irritation or strong odors.
Benefits & What Makes It Different
20% PHMB Concentration
This active ingredient provides a stable, non-chlorine alternative that effectively handles bacteria and algae without dissipating in UV light.
Chlorine-Free Comfort
By eliminating chlorine, this product prevents the formation of chloramines, making it a reliable option for swimmers with sensitive skin or eyes.
High Water Stability
Unlike chlorine which requires constant monitoring, this sanitizer remains effective for longer periods, requiring a dosage of 1/2 gallon per 10,000 gallons of pool water.

When To Use This
Pro Tip
In hot climates like Arizona or Florida, while chlorine burns off quickly, this biguanide formula stays stable; however, always ensure you chemically clean your filter twice a season, as biguanides are heavy flocculants that can load up filter media faster than chlorine.
Common Questions & Instructions
How much Baquacil Sanitizer do I need for a 10,000 gallon pool?
To achieve the recommended concentration of 50 ppm, you should add 1/2 gallon (1.89 Liters) of Baquacil Sanitizer per 10,000 gallons of pool water after ensuring your pH is between 7.2 and 7.8.
Can I use Baquacil Sanitizer in a pool that currently uses chlorine?
No, this product is specifically compatible with the Baquacil Pool Care System; mixing biguanides with chlorine will cause severe water cloudiness and chemical reactions, requiring a full conversion process.
Does this product affect my pool's Cyanuric Acid levels?
Baquacil Sanitizer does not contain or require Cyanuric Acid (stabilizer), as the 20% PHMB active ingredient is naturally resistant to degradation from the sun's ultraviolet rays.
