BioGuard® balancers are essential to an effective pool program. Maintenance will be easier and you can prevent routine pool care issues from growing into major problems.

When your pool water is balanced, there is the proper ratio of mineral content and pH. Balanced water prevents pool water from being corrosive or scale-forming. Why is this important? Because non-balanced water can result in bather discomfort, cloudy water, and damage to the equipment.

In order to keep your water balanced, you may need to use one of more of the products in BioGuard’s line of balancers. They include products that control scale, prevent metallic stains, adjust the pH and total alkalinity, and correct mineral imbalances.

The benefits of balanced water include:
• Reducing maintenance costs and chlorine consumption
• Preventing equipment corrosion, etching of plaster, and wrinkling of liners
• Preventing eye irritation due to low pH
• Avoiding pH bounce due to rain, swimmer load, and other chemical application
• Preventing serious damage that scaling can cause to pool surfaces and equipment
• Increasing swimmer comfort
• Allowing chlorine residual to work most efficiently

The water will remain in balance if kept inside the following ranges.

Free chlorine residual 1.0 - 3.0 ppm
(parts per million)
Total bromine residual 1.0 - 3.0 ppm
pH 7.2 - 7.8 is acceptable
7.4 - 7.6 is ideal
Total alkalinity 125 - 150 ppm
Calcium hardness
Plaster & SoftSwim® pools
All other types

200 - 275 ppm
175 - 225 ppm

Scale Inhibitor
Reformulated Scale Inhibitor works four times better than our previous formula at preventing scale build-up from high calcium levels. Regular use of this concentrated formula prevents scale build-up on:
• Pool surfaces.
• Piping.
• Filtration & heating elements.
• Effective for up to four weeks.
Also prevents stains caused by iron, copper and manganese.
Pool Magnet Plus ®
Reformulated Pool Magnet Plus is now more concentrated than ever. Our improved formula is even more effective at preventing staining due to iron, copper and manganese. It also eliminates discolored water from metals.
• Use monthly in pools that hold iron-containing fill water.
• Use in conjunction with Sparkle Up® to remove metals from the water.
Balance Pak® 100
Use Balance Pak 100 to maintain total alkalinity. Proper total alkalinity prevents pH from "bouncing" due to rain, bather load, and other chemical application. This helps prevent pool staining, plaster etching or liner wrinkling due to improper pH.
  • For raising total alkalinity
  • Prevents pH change
  • Improves swimmer comfort
  • Prevents corrosion due to improper pH
  • Protects vinyl liners from wrinkling due to improper pH

This product is part of the BioGuard Maintain Category.
Balance Pak® 200
Balance Pak 200 raises pH in pool water. This helps prevent equipment corrosion, etching of plaster, and wrinkling of liners caused by low pH or acidic water.
  • For raising pH
  • Improves swimmer comfort
  • Protects pool equipment from corrosion due to improper pH

This product is part of the BioGuard Maintain Category.
Lo 'N Slo®
Lo 'N Slo is an easy-to-measure product for reducing pH and total alkalinity in pool water. It's safer to use and store than liquid muriatic acid.
  • Lowers pH
  • Reduces total alkalinity
  • Quick dissolving
  • Safer to store, transport and handle than liquid acid

This product is part of the BioGuard Maintain Category.
Balance Pak® 300
Balance Pak 300 is a unique formulation for faster dissolving and less cloudiness. It boosts calcium hardness to help prevent equipment corrosion, etching of plaster and wrinkling of liners.
  • For raising calcium hardness
  • nhibits corrosion of pool equipment and surfaces

This product is part of the BioGuard Maintain Category.
Stabilizer 100
Stabilizer 100 is granular, totally soluble and prevents free chlorine residual loss due to sunlight. Apply it by feeding very slowly through your pool's skimmer. Stabilizer 100 reduces maintenance costs and chlorinating product consumption.
  • Prevents chlorine loss due to sunlight
  • Reduces chlorine consumption and maintenance cos
  • Use only in outdoor, chlorinated pools

This product is part of the BioGuard Maintain Category.

You should take a water sample to us for professional analysis. We recommend doing this before spring opening, mid-season, and before closing in the off-season. This will help you are maintain the water at the proper levels. You can get a container from us or use a clean container from home.

If a problem does occur, we will suggest the right BioGuard balancers so your water is balanced.

NOTE: With all pool care products, avoid physical contact. Follow safety information on label instructions. Open in well-ventilated area. Avoid breathing fumes. Store in a cool, dry place. Keep out of the reach of children.
