BioGuard ChemOut - 2 lb

Quickly Lower High Chlorine and Bromine Levels

BioGuard ChemOut is a pool chemical neutralizer designed to reduce excessive chlorine, bromine, or hydrogen peroxide residual in pool water. When sanitizer levels are too high after shocking, superchlorination, chemical adjustment, or system conversion, ChemOut helps bring water back toward a swimmable range faster so you can reduce unnecessary pool downtime.

This 2 lb treatment is especially useful when chlorine or bromine levels are elevated and waiting for them to drop naturally would take too long. It is also helpful when preparing for certain stain treatments, dealing with metal-related water issues, or converting a pool to a chlorine-free SoftSwim system.

Key Benefits

• Lowers high chlorine and bromine levels: Helps neutralize excessive sanitizer residual in pool water.

• Reduces pool downtime: Useful after shocking or superchlorination when sanitizer levels are too high for swimming.

• Works with multiple sanitizer residuals: Helps eliminate chlorine, bromine, or hydrogen peroxide deposits.

• Suitable for all pool types: Designed for use across swimming pool systems when applied according to label directions.

• Does not affect pH: Helps avoid unnecessary pH readjustment after treatment.

• Helpful for special water care needs: Can be used when converting to SoftSwim or when lowering sanitizer levels for certain stain and metal treatments.

• Direct pool application: Added around the edge of the pool with the pump running and water circulating.

Product Details

Compatibility and Requirements

BioGuard ChemOut is intended for swimming pools where chlorine, bromine, or hydrogen peroxide levels need to be lowered. It can be used after superchlorination, during sanitizer system conversion, or when reducing sanitizer levels is necessary before certain stain or metal treatments.

Before applying ChemOut, test the pool water to determine the current free chlorine or bromine level. Correct dosing depends on how much sanitizer residual needs to be removed, so always follow the product label and dosing chart. Do not add ChemOut through the skimmer.

How to Use

Allow 8 to 12 hours after superchlorination so the treatment has time to oxidize wastes and chloramines. Test the pool water before adding ChemOut to determine the sanitizer level. If the chlorine reading is above the highest level on the test comparator, dilute the sample as directed by the label to get a more accurate reading.

Use the product’s dosing chart to calculate the amount needed. Add ChemOut directly to the pool water by scattering it around the edge of the pool. Keep the pump running and the water circulating during treatment. Re-test the water before swimming to confirm sanitizer levels are back within the appropriate range.

Frequently Asked Questions

What does BioGuard ChemOut do?

BioGuard ChemOut lowers excessive chlorine, bromine, or hydrogen peroxide residual in swimming pool water.

When should I use ChemOut?

Use ChemOut when sanitizer levels are too high, especially after shocking, superchlorination, or when you need to reduce chlorine or bromine before swimming.

Does ChemOut change pool pH?

No. ChemOut is described as not affecting pH levels, which means pH readjustment is typically not needed after use.

Can ChemOut help reduce pool downtime?

Yes. It is designed to reduce swimming downtime caused by high chlorine levels.

Can I pour ChemOut into the skimmer?

No. Product directions state that ChemOut should be added directly to the pool water and not through the skimmer.
