Relax Hot Tub Oxy-Shock is an effective water treatment product used to shock your hot tub / spa. You can use Oxy-Shock on a weekly basis or when the hot tub has had a heavy use. Oxy-Shock can provide the necessary shock without affecting the chlorine or bromine level. Please always read the instructions. Pre-dissolve the required amount of Relax Oxy-Shock in a clean bucket with warm water. Stir in the solution of Oxy-Shock until the granules has dissolved. Ensure that your hot tub circulation pump is turned on before slowly pouring the Oxy-Shock solution directly onto the surface of the hot tub water. Continue to run the hot tub circulation for at least 15 minutes before using your spa.
