BioGuard Chem Out chlorine neutralizer, lowers high chlorine level

BioGuard® Chem Out®
Do you need to reduce your pool's chlorine or bromine level in a hurry because of a shock treatment AND you've got customers coming over in a couple of hours?

Chem Out is a concentrated, granular product that quickly reduces chlorine & bromine levels.

Chem Out will not affect your pool's pH level.

BioGuard Chem Out is also great for the following treatments:

  • neutralizing chlorine or bromine when converting a pool to Soft Swim
  • lowering chlorine or bromine levels when treating severe metal stains and metal problems

When lowering chlorine level after shocking, allow about 8-12 hours for superchlorination (shock) treatment to oxidize swimmer waste, unfilterables & chloramines (combined chlorines) from the water.
