BioGuard professional pool care

Pool care should not feel like guesswork. Explore BioGuard sanitizers, shocks, algaecides, balancers, enhancers, salt-pool products, and seasonal solutions—then let Aquarius help match the products to your pool and current water conditions.
The BioGuard foundation
Three steps for
routine pool care.
The BioGuard 3-Step Pool Care System organizes routine maintenance into three essential jobs. Exact products and treatment frequency still depend on water testing, pool size, sanitizer system, usage, weather, and surface type.
Sanitize
Maintain an effective sanitizer residual to control bacteria and help keep water protected.
- SilkGuard Complete® Tabs/Sticks
- BioGuard® Basic Tabs
- Power Chlor™ and Super Soluble™
Shock
Oxidize organic contaminants, address combined chlorine, and help restore clarity and sparkle.
- Shock Complete®
- Smart Shock®
- Burnout® and Oxysheen® options
Prevent Algae
Use the correct algicide to prevent growth or treat the specific algae already present.
- Algae Complete®
- Back Up® 2 and Algae All 60®
- Banish® and Spot Kill®

Water testing and guidance
Buy what the water
actually needs.
Cloudy water, algae, scale, staining, chlorine loss, and swimmer discomfort can have more than one cause. A water analysis helps separate the symptom from the underlying balance, sanitizer, circulation, or filtration issue.
- 1Bring a representative sampleUse a clean container and collect water away from returns and skimmers.
- 2Share the pool detailsPool volume, surface, sanitizer system, equipment, recent products, and symptoms all matter.
- 3Receive a treatment sequenceSome products must be spaced apart or added in a particular order. Follow the written plan and labels.
- 4Retest when recommendedConfirm the water has responded before adding more products or allowing swimmers back in.
Pool chemical safety
Professional products require responsible handling.
Always read and follow the complete product label. The label—not this webpage—is the controlling source for dosing, compatibility, protective equipment, storage, disposal, and return-to-swim directions.
- Never mix pool chemicals together.
- Add products only as directed by the label.
- Store chemicals dry, ventilated, secured, and away from incompatible materials.
- Keep products away from children, pets, heat, flame, and moisture.
- Do not use a product when the pool type, volume, or current chemistry is unknown.
