SpaGuard's Brominating Concentrate provides spa owners with a one-step bacteria fighter, which is applied simply by adding a few granular pellets to spa water while the pump is running. Brominating Concentrate is pH neutral, so it will not affect your spas pH or alkalinity levels as well as needing no pre-treatments or activators to begin working. This concentrate will eliminate odors and other undesirable compounds, simplifying spa maintenance while creating a healthier and more comfortable spa environment.
